[Poll] What size is right for you for your phone or tablet?

The other day Samsung sent me their latest Galaxy Tab Pro S to play with and give my thoughts on it.  And so far it's pretty neat.  12" is too big for a tablet, but just about right for a laptop.  I'm getting used to it.

But that made me wonder.  What size is right for you?  I'm not big on tablets, but the recent 8" G Pad 3 is growing on me, and I've switched from a 5.5" phone to a 5.3" and I'm really liking that reduction in size.

So, I'm going to ask by way of a poll, and I want to know the difference between what you'd use for a phone and tablet separately.  Please take a few moments and fill the following out.
