Being able to use device with just fingers is great, especially through actual physical keys that give tactile feedback so that you can acccurately operate even small keys, this enables a device to provide instant access to many different functions at once. Plus, with input and output somewhat separated, the precious output space can be dedicated to displaying more information.

What worries me about finger friendly touchscreen is that the screen is roughly 5 by 3 thumbs big, which puts a limit to the amount of inputs instantly available, and it has to be combined somehow with displaying the actual content/information...

On a more practical note, the touchscreen of my N800 and N810 is too insensitive to consistently register fingerpresses without exerting disturbing amount of force. Something sharp works better, except for pressing 'o' on the osk of my N810 and enter in N800, there I need to press with stylus until the colors go funny on the LCD. I dare not even try make it recognize finger in those areas. As I still like to use the device one handed, while holding it, I've become accustomed to using my thumbnail as stylus. It's not entirely free of frustration, because you have to keep nails long enough to register when jabbing the touchscreen, but short enough to not get in the way when typing on the hw keyboard. Still, I manage to both hit links and keys on osk (when nail length is optimal).

If the device had a dpad or joystick on the left, centred vertically, and you could rotate the device to portrait, and there was a browser with virtual pointer like opera mini, or microb jump-to-link that wasn't so random and perhaps with added pointer clue so you knew where you were, I'd probably use the device like that a majority of the time.. Kinda like a traditional phone but with bigger screen... I still browse the web on my phone instead of tablet and normal computer sometimes, because it's more comfortable physically to handle.

I use the tablet the most at home, and probably spend more time browsing web on it than on my computer... It's a compromise in comfort and information-at-once.
