I bought the emachines M6809 from Best Buy and love it. It comes with a dual format DVD burner, 512MB PC2700 SODIMM, 80GB HD, Athlon 64 3200+ Mobile processor, ATI Radeon 9600 mobility Video. It runs windows XP Home, and will run future version of 64 bit Windows.
It's fast, it's stable, it's cool (temp). I did however order a new 7200rpm HD for increased performance, as well as a Kingston 1GB DIMM (Giving it 1.2GB PC2700).
It's a good buy. I aslo got $250 rebates from best buy.
