A tablet is a Gadget, a PC is a personal computer wich are designed to be a computing device on wich you can acces the internet, process text, edit vids/pics and even make your own website. In addition to that developers found ways to run games on it and connect it to TV and homecinema and use it for watching and storing movies and stuff. The fact that it is all upgradable and adjustable to your needs (Video cards, memory, processor, discreader/writer, soundcards, etc) A tablet is like a console. You buy it to carry around and acces the internet and sometimes play small flash games or even EDIT TEXT. All those things can be done much better on a desktop PC and even a laptop. Attaching two weird nuchucks with joysticks and making it able to play games on it that also can be done on a PC won't justify the development costs and the price of over 1000$. For that money you can build an amazingly powerfull computer that can do the same with a lot more and even ten times better. I won't be buying a tablet for gaming. Even if they attach weird nunchucks. If I wan't to game on the go I'll use the Vita wich is smaller and has quality titles on it.
