As far as I can tell I'm one of the first people who is actually living with an i440D day in day out rather than having a 48 hour trial or similar. I've also got the docking station and the handsfree case, which I've not seen any review of to date.

Firstly, the included stand is great. From the videos/pictures I thought it looked flimsy. It isn't in the slightest, although I do wish it was part of the unit, rather than another thing to remember. I'm less impressed by the slip case that comes with the unit; it's far too tight and because of this, the zips are going to end up scratching the case, also it will provide little protection if (for example) the tablet falls and lands on the zip. A neoprene flap would solve these problems, and have been more useful than the dust cloth.

Onto the tablet itself.
Having a 1.8Ghz processor is just great. Ditto lots of RAM and a standard 2.5" SATA drive. The battery retaining clips are OK, but I sorely miss the bridge battery from my old TC1100 for doing a battery swap whilst in suspend rather than hibernate. The built in speakers are really terrible, slightly worse than my TC1100 (and I didn't think that would be possible). I don't know what Hugo Ortega is used to in laptops/tablets, but I'm glad I've never heard them.

This leads me onto my next grumble, the volume buttons. With the fitted speakers they're a waste of a quarter of the buttons on the unit. I would (much, much, much) rather have the buttons control the screen brightness -that's something that I want to vary frequently, unlike the volume which needs to be permanently muted.

Onto the fingerprint reader, which is nice when it works. Unfortunately the supplied software has a nasty habit of forgetting the Windows XP login password, rendering it just a bit useless. This is unquestionably a software bug, but it has persisted through reinstalling the software supplied by TK. There may be a later version for download from their website, but the zip file is corrupt, so I'll never know. Also TK installed a second piece of fingerprint software that is incompatible with IE7 -the FAQ suggests purchasing an upgrade. Why bother including the software on the tablet when it's useless? On the plus side, the scroll functionality of the fingerprint scanner still works, though it'd be nice if it rotated so it wasn't scrolling at 90 degrees to the window orientation when used in portrait mode.

I love the power switch, unlike my old TC1100 it's not going to get switched on by accident in a bag.

Heat and noise. The fan is definitely a variable speed one. Thankfully most of the time it's fairly quiet, you hear it at (I presume) full speed briefly during boot up. The casing does get very hot sometimes, although no worse than any other tablet/laptop I've ever used.

The dual mode touch is just fantastic. I always hated the idea of the palm rejection style touch screens, but the manual switch that TK have implemented is a stroke of genius for which they really deserve congratulations. The only reservation I have is that there are two modes of touch, point and stroke. I find stroke to imprecise for using a finger to click buttons etc. (usually starts dragging instead) whereas point is great, but you can't draw with it because you just produce a dot at the start of the line. If there was some way to combine these based on the whether I tap with a fingernail or the whole finger, that's be even better. I'd also suggest that the beeps are a poor way of knowing whether you're in digitizer or touch mode (especially if you have it muted, which is a must in meetings) and that an LED would have been better.

Ports
Only 2 USB is being stingy, there is plenty of space for more (rotate them 90 degrees if necessary). But only 2 is just silly
PCMCIA I'm at a loss to explain why there is only a type II PCMCIA slot when there is plainly space (and even markings on the case suggesting this was originally the idea) to have a type III, which would have been incredibly useful. Or even an Express card slot to look fancy?
eSATA. Why? It's useless where it is. Remember that eSATA does not deliver power, so the only time you might want to use it is when you have docked the tablet. At which point it is inaccessible behind one of the sides of the dock. No cut out. And, eSATA is not replicated on the dock. eSATA is a feature that I might have found useful, but it's rendered completely useless here by bad design. Speaking of ports covered by the dock, the RJ-45 Gigabit Ethernet port is covered too. But that's OK because it is replicated on the dock...

Ahh, the dock.
What no review I've seen has mentioned is that unlike every other manufacturer dock I've ever heard of, the dock does not pass through the network connection to the internal network card. Nope. There is a USB Ethernet controller in the dock. A 10/100 controller. Rather than the gigabit one in the tablet itself. This is the part of the design that most flummoxes me, because TK have added an extra component, at extra cost to provide a reduced version of something that they already integrated into the unit (the TK accessory website specifies pass-thru in case anyone#8217;s wondering why I didn't notice this before I bought the unit). I know that TK read this forum and I'd be genuinely interested to hear why they made this decision.

I can just about understand that you might not want to risk trying eSATA over the docking connector, particularly if you didn't have anyone skilled in routing high speed traces. But that argument just doesn't apply for gigabit Ethernet.

Finally, the handsfree case is a bad joke, as it covers all the buttons, the speakers, the microphones and the fingerprint reader. I imagine this is why there isn't a picture of case with the tablet installed on the TK website.

Despite all the grumbles I list above, I wouldn't swap the base tablet -it's good and the only inherent faults are minor, and for the most part should be software correctable. But I wouldn't buy the dock or the handsfree case again.

I also have a list of improvements that could be made to an i450 or similar, but it seems unfair to list those here as they're not really relevant to the i440D.


Wow, that was a long post.

If anyone has any questions on anything I haven't covered, I'll be happy to try and answer.

Hi William,
Thanks for posting your thoughts about the Sahara Slate PC i440D. We always like to hear honest feedback from our customers and we appreciate that you took the time to share it with the Buzz community.

I have addressed some of your concerns below:

Standard Neoprene Case
We included the standard neoprene case as a lightweight, portable carrying bag. Thanks for your input about the zipper tabs. We had not heard this complaint. If you are looking for additional protection, we also offer the padded portfolio case as one of our accessories for the Sahara series.

Front Volume Buttons
Yes, the front volume buttons are pre-programmed because home automation is one of our core target markets, and many of our customers asked for this feature. If you do not want to use these buttons for volume control, they can be reprogrammed to control screen brightness using auto-hotfix.

In addition, here is the solution for the turning down the beep that indicates the switch between Pen and Touch.

• Open Control Panel
• Click on “Sound”
• Click on “Speakers Realtek High Definition Audio Working”
• Click on “Levels”
• Adjust “PC Beep” slider to change the volume level

Ports
Based on our board layout, we included just 2 external USB hubs on the unit due to the limited number of ports available to us. Note that several functions, including the touch screen and digitizer also use the internal USB inputs, so the capacity was limited.

As for eSATA, you need to remember that our devices are targeted towards the enterprise business market. Many of our customers require mobile hi-speed data transfer capabilities of eSATA for their applications, therefore we determined that this was an important addition to the device.

Docking Cradle
When we designed the new Sahara Docking Cradle, we were limited by the number of pins that could pass through the Docking Connector. Based on customer feedback, we determined that the most essential external ports were for USB, VGA and 6 wire Firewire so these are the ones that we included.

Once again, thanks for all your feedback which is being passed on to our R&D team.

Battery life is ALWAYS, a paramount issue?

Any experience with the array mic and dictation?

Thanks for your thoughts!

William,

You can't post too much for me on the i440! Keep adding to your comments, don't let lack of response signal disinterest, most are just shy.

Seeing Gail so eloquently address your issues demonstrates Tabletkiosk's commitment to after-sales support also.

PS Gail, while others drop firewire probably solely cutting costs, actually ADDING rare six-pin bus powered firewire is admirable user-focused design approach.

For those who don't know, bus power for firewire far exceeds USB specs and makes self-powered drives and disk burners actually single cord realities.

Anyone who appreciates the data transfer isolation from system drag firewire offers notice seemingly small slate feature with unique value.

Battery Life

All I can honestly say is that battery life is better than the old TC1100. All my measurements are badly skewed by the fact that I usually have a data card plugged in, which saps power. I would say that I am getting about 2 1/2 - 3 hours with the data card working, but that is variable. With the TC1100 I was lucky to get over 2 with the data card in. Particularly since the trains in the UK have power points, I just plug in and don't worry about brightness

Array mic

I haven't tried it. If I get around to it I'll post how I get on, but I don't have anything to compare to.

Responses from TabletKiosk

This was probably the key thing that made me pick the i440D over an LE1700 from motion. If ever I rang motion sales with question they seemed surly and not particularly interested in helping, whereas TabletKiosk were always helpful and answered my questions (and whilst you can't judge support based on pre-sales it seemed fair to assume that a company helpful in pre-sales was more likely to be helpful in support than one that was unhelpful).


Volume Buttons

Gail, would it be possible to have a link for auto-hotfix. I imagine I may not be the last person to be interested in this.


Touch/active button

I think I may not have been to clear on this one, what I meant was that there is no way to know if you are in touch or active when you bring the tablet back from suspend - I am clumsy enough that I might catch the button, or just not remember which I had it set in. An LED (maybe a backlit button) would mean that I knew at a glance. I know this sounds petty, but it is something that I have very definitely found myself wishing for.


Ports

This one may be stirring the pot a little, but I seem to remember a post from SteveS (it might have been at GBM rather than here) saying that someone at TK had told him that the main board didn't fill all the available space inside the tablet. Given that the footprint for a modern USB hub controller is about 5mm x 5mm (and not a lot of power components that need to go with it) I am surprised that there wasn't room to incorporate one. I do see the problem with physically fitting in more ports though since the casing does not seem thick enough for a double or ports rotated through 90 degrees (that one is always horrible to use though, so I'm glad it's not like that)

eSATA

I guess if a large number of customers want it, it goes in. I'd love to know what they could be using though and what its power supply is. I personally know of nothing that uses eSATA that does not require a power brick.

Firewire

I have seen enough people using firewire with video cameras to think that it's a good idea even if I know I'll never use it. I do want to point out that a) the PX-608CU DVD writers powers quite happily from two USB ports b) the USB spec does not specify that you cannot deliver more that 500mA or current, merely that you must be able to supply 500mA if the device requests it (I forget what the minimum that must be supplied without negotiation between the host and device, I think it's 100mA). Sorry, but people misquoting USB capabilities is a pet peeve of mine, as devices with the wrong type of USB port (for example a camera with a full size A receptacle). Back to tablets now :)

Docking Cradle

I'm still at a bit of a loss - by my calculations, each USB port needs 5 pins on the connector (obviously if using a hub in the dock there is only one USB port passed through, but I don't know this and am currently travelling and away from my dock so can't check this). Firewire will need 7, VGA needs 16 (assuming not using a common ground). Which makes 28 plus the 4 power pins (assuming a hub in the dock. Without a hub, it comes to 43). Ethernet would take a maximum of 10 pins.

This doesn't take into account any requirements for separation, more grounds etc. but it does include a reasonable number of grounds and whilst I'm far from an expert on routing high speed traces I still don't see how the connector can be full, especially since it's a pretty high density one.

I reread my original post and realised that it sound awfully negative which is not really fair as the i440D is a very nice tablet, and I wouldn#8217;t want not to have it. It's just easier to pick up on the things that are wrong rather than the things that are right.

Hi William,
Try this link, it should help you out with the auto hot key to reprogram the buttons.

Dredging this topic back up, I've now got comments on TK support. I didn't post more about the unit, because it started suffering intermittent but frequent (hard) lockups and BSODS (and also in memtest). TK were very helpful, having someone on the end of a phone, talking me through how to replace the memory in the slot on the screen side of the board. However, after a few months (and ridicule from my colleagues about "how long before it crashes" in meetings) the problem returned and I'm shipping it back to TK for them to inspect it (and hopefully fix it).

The only blot in the copy book (apart from the fact that the damn thing broke in the first place) is the extreme reluctance from TK to have me ship it back to the USA originaly, when now they are only too happy to do it. Unfortunately because of that I'm going to be selling this unit once it's repaired and shipped back to me, because it's just become a perpetual joke now if I turn up at a meeting with it (I was given a cheap X60 so I could "get some work done rather than waiting for that thing to crash")

But I will post my experience with the RMA procedure once I've been through that.

I'll try and run a battery test in between me getting it back and me selling it -something I would have done before, but it currently doesn't get through one battery discharge cycle without locking up.
