I'd love a joystick like the PSP or the zodiac for games.
And I've mentioned this before but for the webpage scrolling thing, I'd REALLY love a blackberry-style scrollwheel on the side of the screen!
On the Dpad:
On the N810 the center button is too large and the directional keys are FAR too small and offer too little tactile feedback to really enjoy a fast moving game. I'd much prefer a + style gamepad, (maybe in the Gameboy style?) with pressure sensitivity or a joystick similar to the PSP's
I'm pretty sure gaming was not intended as a significant use of the device... unfortunately. Maybe a later iteration...
Hmmm this is a very good point... The zodiac on the other hand, IIRC was intended specifically as a gaming device.
However, that doesn't necessarily mean we can't dream about/request better gaming hardware. I know I use my N810 for games all the time and I would be using it a lot more if I had a good joystick or a decent d-pad
