I've had MacBooks for 7 years now, but need to get a PC to run Autocad for design school. I want something very light and portable, and not too expensive. I will only be using it for Autocad. I will probably get a mouse and inexpensive moniter to make working at home easier as well. These are the requirements to run the program: 2 GB RAM 1.8 GB free disk space for installation 1,280 x 1,024 true color video display adapter 128 MB or greater, Microsoft® Direct3D®-capable workstation-class graphics card Microsoft® Internet Explorer® 7.0 or later Any suggestions?
