As a Office 365 subscriber and OneDrive user, this is fantastic news.
Amen to that.
I get 120GB of Dropbox space for $10 a month.
For $100/year, you'll get 1 TB of OneDrive space plus access to 5 licenses of Office for OS X and Windows plus 5 more licenses to Office for mobile platforms. If all you need is one Office license, the personal plan is $70/year. Both options can be had for even less if you know where to look. I got my Office 365 Home subscription with a keycode on a card for $80.
