Do NOT Get a netbook. The only ones you find that cheap are netbooks. Try a Lenovo IdeaPad Y510 - Its a pretty good laptop for $400-ish bucks, and has a huge screen that you can watch movies on. Its $700 new, but on ebay their only 400 because the laptop is from 2007. I have it and I love it

Specs:

Intel Pentium Dual Core Processor
Windows Vista Home Premium
2.00 GB RAM
Mobile Intel 965 Express Chipset Family

Its pretty good, I like it
