I'm out of space on my Macbook Air and thinking about ways of removing things. One idea is to put all my music (~100GB) on a big thumb drive (y, and back it up). I pretty much always have my keychain so this is only a slight inconvencience. I would symlink that directory to a folder on the thumb drive. Has anyone done this? I know some people won't like the idea due to thumb drive irreliability but I have had good luck.
