I have large fingers, I almost have to use a stylus just to unlock the screen on my phone. I have no problem unlocking the TAB 2, but still have trouble making a selection in many places and almost always switch to landscape to use the keyboard.
As for touchpads: I had to disable tapping, I could not ever use the ones on my (any) laptops without generating false
clicks
I read 1 handed (mostly, right) on my PEz. I can't see how I can securely hold AND tap/swipe, 1 handed (tried on my TAB and failed (=dropped (safe, was reading in a soft bed

) )
