Check out amazon.com. You can find some great deals, way better than best buy, they have good return policies, and if you buy an ASUS like I did, it comes with a two year warranty and a year accidental damage warranty.
Oh, and mine has an i5 processor and it plays games and does everything I ask of it just fine. I was thinking about waiting for the Sandy Bridge, but for me it just wasn't worth it and I'm glad I didn't wait. They reportedly do have some copy protection built into the chip that will make it harder to torrent, if that's your thing.
