I now mostly use my PS3 for gaming. I started out with consoles, but then switched to the PC primarily for online gaming before consoles really supported that. Then after getting the PS3 I was hooked and now use that as my gaming entertainment.
I love my Nintendo DS. It is so convenient, it is usually always in my purse. I enjoy Mariokart, all the Professor Layton games, Super Princess Peach, Diddy Kong Racing, Zelda, and Super New Mario Bros.
