Thats up to you, but I think them being as cheap as they are, and you knowing you won't have to worry about settings, etc is a very good thing.
Basically, if you buy one of the next gen systems, your buying a grand+ worth of PC parts for the price of a console.
Plus sometimes, I prefer to play infront of a tv in the living room to playing on a smaller monitor upstairs in my room, where at the moment, its soo cold, brrr...
Plus having to keep up with technology, etc.
