Re: Another "Laptop for College" thread...
You don't even need Vista! For just Internet, movies, and music, even an ancient (well, old) laptop is capable. My ThinkPad A21p running Ubuntu Linux can do all of those and it only cost me $150 on eBay, it has a Pentium 3 850MHz and 512MB RAM.
If you're still dead set on Vista, you'll need excessive RAM. 1GB IS NOT ENOUGH!!!!! My parents have 1GB and even 32 bit Vista lags unusably slow. 2GB should be sufficient for just those things though, 3GB is good if you plan on multitasking, gaming, photo editing, etc.
