Last year I found a nice 500GB external at Best Buy for like $70-80.

I found that it is best to shop around a bit though. At different stores, even smaller hard drives cost more than the one I found. *shrug*

Since I carry my laptop between two houses, though, I really just use it as data storage/backup. It's too cumbersome to carry around all the time.

Come to think of it, I'm running out of space on my internal (only have like 20GB left). I should do some maintenance soon. :x
