How do you feel their security is? I get nervous about services like these because of info I would keep out there. Source code, personal documents, etc, etc
They have a free 2GB plan as well.
I keep my password safe file on DropBox. The rest of my stuff, personal, confidential. I don't bother encrypting as the loss of connivence is greater than the risk/cost of exposure.
So - Dropbox should not be used for any important files. But for everything else it should be ok.
unfortunately not available to canucks.
