Yes different form factors used for similar things... so should the user interface part of the form-factor? Since ITs will get even more powerful should they provide konqueror power, hildon file browser simplicity/safety, or both? (By default/out of the box/fully advertised)

The sheer nature of the high dpi screen for internet surfing requires immersion in the interface while big buttons are on the side for easy navigation? This contrast of DPI (squinting at a portion of the screen while big cheerful buttons on the side) shows different expectactions about depth of user interface.

Nokia should have different resolutions like 3/4 (um 600x360) for use as an accessory and full dpi resolution for power use... and i think different window system for each. That might mean konqueror for full dpi and simple hildon for 3/4 mode.

Or as much as i hate to say it... an iphone interface and a full linux interface. Iphone looks to be a perfect 'accessory' interface which i would love to use while driving or not paying attention, but the IT's full resolution shines when using in a power mode like web surfing or full linux distro. Its distracting to mix the two into a single ui... that would require separate mp3 player, email, im, and maybe maps and calendar/pim features to be refactored for accessory use (out of the box)
