Also looking at your profile, I recommend the DS as well. It seems to match your gaming preferences more than anything else. In home consoles, my honest view is:
Wii: Wait 6 months. You'll have Galaxy, Smash, some good 3rd party games, and Mario Kart and and many others right around the corner. You'll also have the launch of Wii Ware which looks to have some great cheap priced games.
PS3: Wait until it looks like it can maintain acceptable sales. By maintain I mean you obviously don't want to look at sales right after the price drop as necessarily permanent. So, like WoW said, we need to see if it can survive.
360: Without question the best game library right now, but there are some reports of falcons overheating coming out now. This means that even the newer models MAY not be fixed. Like the Wii, wait 6 months. We need to see if the reports keep coming and getting more frequent or not. There also may be another fix announced in that time.
PSP: It's a little lacking right now in genre diversity. Most of it's best games are sports, racers, and shooters. However, if you like to play old games, it's a pocket emulator so you can carry around all your old favorites with you. I use mine for this purpose.
DS: This system covers every one of your favorite games. It's cheap, it's got good battery life, it covers a great variety of genres (except Shooter), and has the vast majority of announced current and future 3rd party support. Get this.
Those are my opinions. Welcome to VGChartz!
