I'm a pc gamer through and through. I do own the xbox 360. I think anyone buying them these days is cheating themselves. In 2005-2006, it was a pretty nice addition to any home theater. I don't really believe anyone can argue that. I'm glad I didn't buy the several hundred dollar HD-DVD accessory, that quickly dropped to $50, and then disappeared. Then along came the PS3, and with its blu-ray / linux, it was also a pretty sweet addition to any home theater that needed a blu-ray player, and all around media center type device. It wasn't long however that PC's, I think, took back the lead though in the home theater front.
The only console anyone should consider right now, is the xbox 360 and kinect, and maybe the Wii, but specifically for the entertainment of children. However, the DSi can get the job done, maybe even better. Also, the smartphone / tablet can entertain the kids too. I got a very protective case that enshrouds my Motorola Bionic in a suit of armor, so I have no qualms with handing it to my 6 yr old, to play games, like when in the car.
So, nobody should be buying any consoles anymore. Invest in a solid PC and a smartphone and/or tablet. If you have a lot of kids, then look at the DSi as a possible solution. I really hope society as a whole, doesn't have too much extra free time to be gaming all the time and complaining what I laid out as insufficient, lol!
