Dropping Dropbox – what's a replacement?

I loved Dropbox and Mailbox. I was paying for a 200GB account. But after learning that Iraq war starter, torture promotor, and warrantless wiretapper Condoleezza Rice will be joining Dropbox's Board of Directors I deleted my account (Dropbox doesn't issue refunds, so I lost about $100. They can keep it.). I also deleted the Mailbox app from my phone.

Now I want a Dropbox replacement. Something that offers cloud syncing. The website Drop Dropbox has a few suggestions: Box.com, Microsoft OneDrive, SpiderOak, and Google Drive. I'd like to hear from Boing Boing readers who've had experience with alternatives to Dropbox. Please post your comments in the BBS!
