Tablet PC and Zbrush

[WitchKing]

Hi guys,

I'm a complete noob to the wonderful world of tablet PCs, and am looking to pick your collective brains for some help, if possible. :hail:

Can anyone recommend a tablet PC that could comfortably handle primarily Zbrush 3, as well as 3DS max and Photoshop?

I've been trawling the various threads here for a while, gauging people's opinions, but the more I read the more confused I get!!

I'm a professional games artist, and need a laptop that I can draw on in Zbrush, but that can also function as a standard laptop (so slates are kind of out of the question), and have seen various convertibles, but dunno where to even start.

I guess my main criteria are:

Needs a decent screen size/resolution to see what the hell I'm doing! :P
Needs to be powerful enough to throw around a couple of million polys in Zbrush.
Needs to be able to handle 3DS Max and Photoshop - I guess decent cpu, video card, ram etc. are all pretty vital here.
Wacom-type pressure sensitive pen input is obviously, pretty important :)
Cost - doesn't really matter.

Any ideas? Or, as I suspect, is it some crazy pipe-dream I'm having?
