While Dropbox is the most popular shared-drive mechanism out there, there are alternatives to it.

1) Google Drive - took my a long time before I even tried it, but it works about as flawless as dropbox for my needs. I actually like it a lot as I use Google Docs heavily, so it makes it easier to use those tools.

2) SkyDrive - offers the most base storage than the other. Has nice support for MS Office products.

3) AeroFS[1] - While it's still in beta, it looks promising (it has limited (android) to non-existant (iphone) support). [1] https://aerofs.com/

I can vouch for AeroFS. We're using it internally for sharing large documents around and it make it really painless.
