Box, an online storage service, is offering 50GB worth of online storage to Android users. They offer a service similar to all the popular cloud storage servers like Dropbox, and iCloud.
To be able to get your 50GB, all you need do is go to Android market and install Box. After you login or register, you are automatically given 50GB which I think is very cool.
This offer ends in the next 30 days, so if you own an Android phone or tablet, head on over to the Android market and download BOX
