In another thread, I wondered what the heck a "mini-tablet" would be useful for besides a pure consumption device (which is useless to me).... So I did a search for mini-tablets with active digitizers and came across..... a phone: Sony Xperia Z Ultra The idea that you can write on the screen with a proper pen (metal-tipped) or pencil is fascinating, along with the little bluetooth "phone" companion device for actual calls since you wouldn't want to mush the giant phablet against your face. From my point of view, this size is certainly nice for media consumption and games, but the ability to properly hand-write notes along with the fact that it's actually a phone lends a lot more functionality. Interesting. Sony's huge Xperia Z Ultra comes with a small companion: SBH52 Bluetooth Handset [video=youtube;mcdMfGQNAKM]http://www.youtube.com/watch?v=mcdMfGQNAKM[/video] Now, I commented in that other thread that Surface RT wouldn't make sense in a mini-tablet because by definition, Windows RT comes with Office 2013 RT--useless in that form factor. But I didn't even think of the phablet angle: If there was a Surface hardware version of a phablet like Sony's but with Windows Phone 8 OS that could pair with other Surfaces, that would be nifty. Well, though the Sony XZU apparently has a very custom display. Color me intrigued.
