I agree and disagree. I am a business person whom does see a great value for a more mobile computer that has full windows and a touch screen. What I believe is the problem with UMPC's is that they have the right idea but wrong form factor.

What is needed to attract mainstream users is a pocket version but not a PDA size, a larger pocket form factor. What I mean is a jacket pocket which can handle as large as 4.25" x 7.5" x 1.3" or so roughly. That can provide modern versions of great form factors of the past like the old Psion 5mx and Revo and HP Jornada's.

Samsung actually has created such a device but unfortunately they do not sell it outside of Korea. The samsung sph p9200 which is the second generation of the p9000. It is tri-fold and has a 5" screen yet folds to the size of a compact disc jewel case.

We need more innovative jacket form factors to gain mainstream users. There will always be a nich for larger 7" models but they will never be mainstream due to two factors one is the price and the other is most people are more comfortable and prefer a touch type keyboard.
