I'm using one to reply to you....
Yes, they are. Get used to having to use 2 hands though, that is the only downside I've found so far.
Screen is lovely, especially the sides, they fall away, so when you're swiping left or right, there's no material to catch your thumb on.. You'll see/feel what i mean when you have a play with one.
So much extra as well with ICE on. The only downside to that, Sky haven't configured it yet for Sky Go ! Grrr
Anything else you want to know, just ask.
