You can get $400 off an HP laptop with an i7 CPU. I just ordered one of those laptops for my brother in law who will be using it for CAD work. I got it with the i7 CPU, 8GB of RAM, and a whole bunch of upgrades and accessories including Microsoft Office 2007. The total came to about $1,350 after tax and shipping. That's a GREAT deal IMO.
