Box have been on somewhat of a roll of late. They've been offering out free storage to LG and Sony
Ericsson owners by the bucket. Today they updated their Android application bringing with it some new collaboration features, and for a limited time only free 50GB worth of storage for everyone who downloads the app and logs in before March 23. I didn't get an additional 50GB, so we'll say that it probably doesn't apply if you already got 50GB free out of them before.
One of Box's stronger features is its collaboration tools, and now right from within the app you can invite people to collaborate on your files. They also put in support for commenting on individual files too. Pretty nifty.
The UI also gets updated, and now makes use of the standard action bar. Another useful addition is the ability to batch multiple file uploads at once and the app will now support being moved to the SD card.
Box are definitely going big, and while Dropbox is preferred by a good chunk of the market -- free desktop sync helps -- 50GB for free is too good to turn away. Hit the download links below to help yourselves.
