I definately want a umpc with a touch type keyboard but I want it small enough to fit into a jacket pocket. I would want a HP umpc that was the same size as their old Jornada 720 which was 3.6" x 7.3 x 1.3" roughly. That provided a keyboard still able to touch type and it would fit into jacket pockets. That size enabled 1/2 vga display so you see the same width as a normal screen.

I do not see the advantage of this as it is too large? It does not differentiate from subnotebooks, etc.

Size is important because of the screen resolution. My eyes are getting too old and I prefer being able to see a period rather than a dust blotch on the screen.

But will this screen be scratchable?

Sorry your age is affecting your eye sight but I do not think the mainstream users agree with the need for such a bulkly umpc. A UMPC should bridge the gap between a PDA and laptop. This HP device is like their old windows ce hpc jornada 820 which sold very few in comparison to the Jornada 720 and 728.

What is missing in the umpc market is a pocket laptop the size of the many old clamshell hpc devices which sold over 2.3 million a year not another device too large to carry without a laptop bag or "man purse"

Actually, what is missing is the "real" Ultra Mobile PC. No company has built one. The original intent was a small touch screen PC at a convenient price. Instead, we ended up with old technology. We need the slate style, good resolution, and long-lasting battery life. Instant-on is also important or fast boot time. Pocketable is definitely not a requirement because pocketable forces the screen to be even smaller than necessary.

I disagree a bit in that slate device have never been very popular in mainstream ever. If you want instant on that is not going to be a full PC OS, it will be Windows mobile/Pocket PC OS. Tablet and slate PC's have never garnered much interest except for niche techies.

If you look at the mobile market the majority of mainstream users prefer a touch type keyboard input not a pen input. The majority of mobile devices are laptops with over 113 million sold each year. What has never been created is a pocket version of that popular form factor, a pocket laptop. Now that technology can enable that, it has still eluded the market as most companies have not a clue what maisntream users want.

The UMPC's have failed due to them not having a touch type keyboard and not being small' enough to be jacket pocket size. As I said look at the history of pen input and there is no good mainstream interest. That is why pen input will never be that popular. Due to the size of UMPC's not being able to be carried in a pocket they then compete against all other such devices including laptops. The result is in 2007 only 350K worldwide sold.
Any device that is not pocketable will be compared to laptops and all other non pocketable devices and sorry but a slate has no chance in that realm.

UMPC's run full windows OS and that is not designed nor do people want anything short of a touch type keyboard. Instant on is not what desktop OS provides. There is a huge demand for a pocket laptop with a touch type keyboard that can rull full windows. A battery life of at least comprable to laptops 2-4 hours would still provide strong demand.
