Ever wish you didn't ask "why"? Anyways...
I've been a long time Console player. I got my 8-bit NES when I was 7, (it was bought with drug money...no I didn't sell the drugs, I was 7, golly) I come from a poor, really poor family and never owned a PC until I was 25. I love both PCs and Consoles, and there are many games that I prefer to play on one but not the other.
I also was Xbox last generation, and the generation before that. I feel I made the right choice, but I am more inclined to go for a Playstation 4 this time around. Looks like it's the better machine, but I haven't ultimately made up my mind yet. Early games are usually not that great and I haven't seen any killer apps yet to make me really want to buy either console yet. I will probably wait a year or so.
