Are you into smartwatch - how about a 3inch screen

[Renegade]

You sure you want to do either when the device is strapped to your wrist? Your arm will be in a unnatural position. We'll surely have an increased incidence of "tennis elbow" when we start using such devices.

Absolutely! This is only suited for tasks that require you to frequently peek into your screen while doing other work on the go. Definitely not for movies or browsing TE.

No need of a touchscreen on everything. A smartphone can still work well with 4 physical buttons. (1 Menu / On / Off, 1 - Back , 2 - Directional scrolling)

On the contrary I feel really frustrated when I have to use a non-touchscreen phone. For SMS and calling its ok to some extent but even while searching for contacts I would prefer a touch screen. I even bought the touch screen kindle coz scrolling using the 4 directional stick to reach the word I want was a total turn off. Now I just have to put my finger on the word and the meaning appears.
