OK, so I just signed up for +Copy
for a few reasons.
1) They have a rather nice console script for Linux. I've always hated how hard Dropbox made it to run it from the CLI.
2) 15 GB, not that I was even using much of the 6 I had on Dropbox.
3) You share the data burden of the files you share, with the people you share it with. So a 1GB ISO shared over like 20 testers would only count as ~500 MB. I've always hated how Drive would double dip on the data used.
Mostly 1 and 3, 2 is just a nice bonusFull disclosure, yes this is my referral link. use it and we both get an extra 5GB
