What gets me about all this hype is that touch screen technology is nothing new.
1. Its been around for ever in some ATM's.
2. Planar has a touch screen monitor for your desktop (required you to plug in a 9pin serial port

3. we had PDA's and pocket pc's for a while (of course they required special smaller apps that worked similar to the normal computer apps) - remember the ipaq. HP still sells a version running Windows.
4. it's been around in tablets for a few years now - there are a number of Windows tablets (although apple does not have one outside of the axiotron modbook).
5. restaurants have the touch kiosks/pos systems.
You know what is lacking - voice recognition. yeah that has been around for a while, but is still very fustrating to teach and get working properly.
but since we are on the subject of touch. what i would like to see is a device about the size of the long rectangle DVD cases, that had all the ports of a laptop (USB, firewire, audio in/out, power adapter - basically what is on a macbook now). Has a good size hard drive, wireless, bluetooth, and a built in slot loading superdrive that is capable of running all my current laptop apps, has about 2-4 gb ram, and a good battery life (4 to 5 hrs).
I mean lets talk about a modbook about the size of a dvd case (ok to be as thick as macbook, mm mabe a little thinner - but don't lose the drives). then beef up the voice recognition capabilities and touch capabilities. Now you got the awesome portable for the businessman, student, field tech or someone who works on the road (photographer, tv crew, whatever).
Basically a cross between:
