Depends what you're into. The Wii is cool to play with a bunch of friends and all the athletic games that have you playing baseball, golf, running, etc. If you tend to play by yourself, the Wii gets old pretty fast. The PS3 is a stunning piece of equipment, has Blu-Ray which would be nice if you only have a HD-DVD player or a 360 w/HD, or are looking to get into high def. But there's a real lack of games for the PS3. They keep saying there'll be more out, well.... If cost there is the cost difference and depending when you want to pick one up, good luck find a Wii right now (other then almost double on e-bay)...
