I don't like tablets. Not the way they're being used.
A tablet is wonderful for a few things, like 1:1 manipulation of objects if you need to do that, or for drawing, gesture control, messing with pictures...
Like for example on the Nintendo DS with the touch screen it is great for certain things like with Rune Factory where you have to manage a field of crops, it's more intuitive and easy to be able to touch them directly.
However with something like The World Ends With You it is more of a gimmick where you have to attack by slashing and tapping the screen and stuff - things that are better done with a button because after a while you start to get fatigue pretty fast. In a case like that a pointing device is more precise and less strenuous. Similarly scrolling and editing and manipulating things on a more abstract level is better done with an abstracted device which minimizes your mechanical effort rather than increasing it.
