This is NOT shameless marketing, but the first list of 12 "free" cloud storage options including the big guys, Dropbox and iCloud.
Now, mother is talking. So listen!
If these guys didn't already know that you are undisciplined and will exceed your free limit, they wouldn't give this stuff away.
The flip side is that like me, you'll sign up for a bunch of these, store the obligatory 2gb of free stuff, usually pictures, videos, and music, and then forget you did it. Of course the bookmark is probably buried in one of the three browsers you use, but as soon as you forget the name of the provider, the "stuff" is totally out of sight and out of mind.
What happens 10 years from now to all that forgotten stuff of your?
