As for cheap laptops: I recently bought an Acer laptop which was ~£300 GBP (about $450 USD?) with 1.8ghz intel c dual, intel GMA 1308mb gfx, 15.6" widescreen, 3gb ram, and almost up to 4 hours battery life. That was the best spec I could find for that price.. (about 3 months ago). So that was basically to give you an idea of what you could probably get.. If you wait a year then you could get one cheaper, although if you manage to pick one up during Black Friday you can probably get a really decent laptop for a cheap price.
