It's split between three big players this year.
The core feature Samsung has been touting all MWC long has been the ability of its tablets to run 4 application windows at once. Useful, of course, but… Nothing else?
How long have you been dreaming of a curved mobile phone? Me neither, but the engineers at LG are very happy with its curved battery and screens. The phone doesn't feel specially awesome either.
Speaking of dreams, we've been always waiting for a waterproof tablet, don't we? No? Yeah. Sony thinks otherwise. In any case, after seeing the impressive feats of the HZO guys I'd rather purchase a water-proofer from them and use the tablet I like.
