We just bought one for DD- her graduation gift! She loves itActually my friend just got a REALLY nice HP laptop, one of the higher end ones for about $580 at Best Buy. It had 3 GB of ram, a 320 GB hard drive, a nice processor (at least a dual-core, but I don't remember) and it looked very nice. It had a good graphics card, too.
Believe it or not, but we shopped around and it was cheaper at Best Buy than it was at Costco!
