>> You, or your company can create whatever apps you need and install them direct without going through the app store.

How? Without jailbreaking? I'm interested, not questioning your knowledge.

>> It's not that touchUI on a desktop isn't practical so much as the desktop's form factor isn't practical for touch

I don't think I see the difference. Seems largely semantics. Touch UI on a typical workstation setup (better?) is impractical. At least right now. I realize it's chicken-and-egg, but I disagree that the best way to solve this paradox is to thrust ALL existing Windows users into a touch-optimized UI in the course of one version.

Instead, bring the technology to niche markets (ala iPad, and industry-targeted applications) and let it trickle down. It may be the slow approach, but when it comes to drastic modifications of workflow, that's probably for the best.

The mouse has been around in home and office computing since the 80s. It may be dying, but I don't think it's going anywhere overnight.
