Here is what TabletPCReview has to say about the Kohjinsha SH6WP10A UMPC powered with an Intel A100 processor:
I would recommend this to anyone wanting to get a UMPC because this thing can be a regular laptop, then switch to a Tablet PC in a second. If you like videos, iTunes, Internet surfing and typing, this computer is for you. If you like games, intense graphic editing, then this computer really isn't for you. I used Vista for the review, but decided to switch to Windows XP tablet edition 2005 after and I love it. It's good on Vista, but it runs better on Windows XP.
I also think that Vista is too much for this little device. XP will run perfectly though Vista is a lot better Operating System for Tablet PCs and UMPCs.
