I don't like the wii. My parents even played it for a few months until it began to collect dust. They rented just about every good game as well.
The 360 is complete win, no doubt about it. They have a similar user interface to wii (characters and all), and soon they will be coming out with a cool thing that's just like the wii, except you use your body to control the game, no controllers, just you. http://www.xbox.com/en-US/live/projectnatal/ check that out. It looks promising, and there are live reviews done on it already. Hehe, microsoft is a great competitor, I have a feeling this project natal will be the downfall of WII! mwahaha... sry...
I'd say it has the best games... You can play a ton of old xbox games on it too.
Xbox 360 can play HD, movies, games, music, videos you have on your computer can be played on your tv... The xbox 360 live is probably the best online service out there. It's 50 bucks for 12 months, and for less months its still affordable... compared to everything else you have to pay a monthly fee that really adds up. There's so much to do, so many updates every day.... I don't see how ps3 or wii can even come close to being as good.
People complain about the red ring of death, but maybe they're doing something wrong. I've had the first model since many xmas's ago... And it has been sitting in the same spot for years, no fan, not a thing... just my 360 on the floor, being played for long periods of time and everything. The only time I've ever had the red ring of death is when I spilt coffee on my HDD. It was back to normal after it dried.
Sure PS3 has blu ray, woopity doo! That's about all it has going for it. It has less games, and more importantly less good games... way less than 360. Most of the great ps3 games are also on the 360 console. A lot of the games on ps3 are even worse looking than 360. You also do not get a mic from ps3 for live, you'll have to buy one for a separate device then use it for your ps3.
