Today, the PC is the first route I would suggest. Both 360 and PS3 are using 6 and 7 year old technology and even longer, which is a lifetime in the computer industry. Everyone is expecting the Nextbox and PS4 to be released some time next year. My second 360 just crapped out and I won't buy a new one. It just seems like a silly time to buy one now. You definitely won't be getting bang for your buck.
With the Wii U releasing to less than stellar reviews, I would also avoid that route as well.
It sounds like you have already decided anyway. I completely agree with your decision.
