Where? So I can sign up.
At 12 bucks a year for 20GB and the iCloud Drive integration with Yosemite, I am most likely going to drop dropbox. Anything extra can be thrown to Google Drive.
I have 50 GB on Skydrive, 50 GB on MEGA, 50 GB on Box, and 25 or so GB on other services and I don't pay a dime.
I pay attention when they have specials, 5 GB here, 1 Gb there. IT all adds up. Plus earn more for referrals. We all have 12 email addresses. Refer yourself to add to your current account GB count using each of your emails.
Start with MEGA - Thats 50 GB just for reading this post.
