No "hi" or anything as you have to act now and quickly.
Microsoft for whatever lame excuse they present, are cutting out previous 25GB storage down to 7GB. So you can compare: Google Music allows 20,000 songs with a 250 MB limit per song which means in theory you can store up to 5TB. Dropbox uses a horrible of 2GB....
So go to https://skydrive.live.com/ManageStorage
NOW (Do not even keep reading this post) and claim your free 25GB even if you dont use it for anything because simply you never know.
