Not sure if you guys know about DropBox (a way to store your files on the Cloud for free).
https://db.tt/eZxuD2JSign up with this link and you get 2.5 GB instead of 2.00 GB (I get +500MB too on my account).
Very useful to store photos, homework, etc (instead of carrying on a usb key) and it synchronizes on all your devices (computer, phone, tablet)
