I'm not sure how practical this is for full web browsers.
I know everyone says "ooh look shiny" when they look at iPhone/iPod touch, but the fact is that if you need to be able to allow full integration w/ Google Maps and the rest of Google's applications (note: Apple cheats by shipping their own Google Maps UI), then trying to trap user interactions is a disaster (which is quite visible from the bad compromises we've made for the tablet browser).

For any other application that doesn't have to host full applications (i.e. flash embedded into an application has the same problem as a web browser), then finger friendly whatever may be better, but those aren't my problem spaces, and I don't own ui design, so I'm staying away from them.

Some of our problems relate to trying to counteract some bad kernel/x behaviors (they're fixed in newer internal builds, which means we can remove some of our bad hacks), and some of them stem from trying to implement bad design decissions from the platform (dragging a web application with a finger, see earlier complaints).

If you're looking for another case where things don't work correctly, try typing into google reader's main screen using the n810's keyboard.

I was pretty sure that the bad dragging/scrolling hacks were in microb-eal, but I can't find them...
