Anyone here still using dropbox? If you aren't it's a pretty slick backup and I suggest you sign up (2GB of free storage).
Currently if you are using this you can boost your storage by testing their beta and auto importing photos/videos, up to 5GB more free!!
I did this myself yesterday. I just put a few of my MP4 movies on a pen drive. Opened it from Windows explorer with Autoplay and chose the 'Import using dropbox' Voila, I now have 5GB more space in my dropbox that I'll never use.
If you don't have an account and want to try this out, us the link below to sign up, you'll get another 250MB free on top of the 2GB. Once you sign up and DL the client, replace it with the beta from the other link below and test the import functionality they are adding to autoplay (Note: You can also do the test from a beta of an updated Android app they are working on if you have such a device)
Sign up for dropbox here for an extra little boost to storage: http://db.tt/WC76cGx
