You can selectively choose which directories to sync per computer (https://www.dropbox.com/help/175/en).

I guess it will. I bought Dropbox one morning in a panic when I thought my drive was dying. It turned out to be fine but I've been working out of the directory since then. Thanks.

Dropbox's Selective Sync feature would solve this problem for you, no?

You can exclude certain directories from synchronizing to your laptop if you want to.
