That's some contradiction and ******** in the same sentence. For the most part all tablets are scaled up larger versions of their phone counterparts.
Why is it a contraindiction ?
Its not true that tablets are scaled up phones. For one thing the android OS was originally separate for phones and tablets - they've mashed them together now under Ice Cream Sandwich - but they still have different code running and different features.
Go into a shop and play with some android tablets. They suck unbeleivably. They are glithcy. They freeze up when opening up things. Whereas ipoad is smooth and glitch free. So for that reason I got an ipad.
Android phones on the other hand are not glitchy and run as smoothly as you woudl expect. And in general I find the use of space on an android phone superior to iphone. I also prefer the android interface in that size (which is different to android tablet interface) - its more functional and better for mutlitasking and jumping between apps than iOS - which to be honest I find juvenile on a phone - its to blocky and mp3 player ish to me
I got an iphone at one point and returned it in less that a week. Went back to my 2 year old Android phone which is better.
