hi Slortar - In my opinion (and experience) yes it is. The 'one touch' buttons when combined with the BookPilot software makes it a worthwhile purchase on its own as the scanning process is hugely simplified and much more practical than anything else I've used. As for the scans themselves ...well for the most part the 'SEE Technology' helps to give a good scan. However it can stuggle with smaller paperbacks and you need to manipulate the book in order to reduce spine shadow. For larger titles (i.e. the more standard size text book and above) there is zero spine shadow.
Although the scanning of each page is reasonably fast (this of course varies accordingto size of page and resolution) you are limited (if using the scanner as it is intended to be used) to only being able to scan a single page at a time which is slow but as you use it more you move yourself in to auto mode and the process goes quite fast..well I think it does anyway.
Best of luck with making a decision. keep on going through the opticbook threads on here and if you haven't been there already have a look at the scanner section of the StudentTabletPC Forum - http://www.studenttabletpc.com/forum...forum.php?id=2 and Tracy's excellent review of the scanner - http://www.studenttabletpc.com/2005/..._scanning.html
Hope that helps
Love & Peace
