I'm a convert to Google photo now :P

Free, unlimited space, apps to auto upload, pretty idiot proof. (your mileage may vary)

Wired have some info:
The Coolest Stuff You Didn't Know Google...

Are you using the app ? Must admit all the editing I've done on docs and spreadsheet have been on the pc. But the app for the ipad works a treat for me for uploading and downloading stuff.

Google drive for me, oodles of space and apps that work on Apple products to enable you to upload, free, can access from any pc anywhere.
