Box app on Windows 8 giving 25 GB to HP users is a cloud storage service which gives you 5gb for free. Today they updated their box metro app for Windows 8 and when I signed in on my HP notebook, it said that I have been upgraded to 25GB for life time, thanks to HP. I think HP have made some agreement with them which means that if you have some HP hardware you may be eligible :)

Just wanted to share this with you.
