I believe that the 'shape' of the current smartphone's market does not happen purely by chance.

If you poll 1million qualified potential customers, i'd bet that a huge majority of them would prefer a pocketable computer-like device, with a touch optimized interface.

Why? Because they probably already have a computer at work, at home and/or in their bag to do their cmputing needs on while not mobile.

Squeezing a desktop app without ui optimization to a sub 4" device is a recipe for pain. Sure, one's initial reaction to it would probably be "wow, this is neat. It's JUST like on my desktop/notebook... Only smaller!" (well I at least I've had that response in Zaurus days). But after spending sometime with the unoptimized UI, you'll likely realize that using a desktop interface on a handheld device is painful and inefficient. Sure, you can train and practice, create macros and scripts to ease the pain, but if you take a step back, you'd probably say 'there's gotta be a better way than this!'.

On the other hand,of you're talking about desktop apps with custom/dhnamically scalable ui that becomes touch-friendly when that same binary is run on a pocketable system, then I'm all for that.

Defaults to touch-ui for daily tasks in mh pocket, with an option to fallback to it's 'full' ui when needed; and also will default to desktop interface when the device is docked to a big screen with desktop-like input devices.
