I use Google Drive / Google Apps as if they're a virtual PC with everything hosted remotely.

I don't synch anything locally - I access it online from whatever piece of kit I have in front of me, which often isn't mine. I don't want any of the files stored locally - I want / need it all to be 'in the cloud'

Is this going to affect my ability to do this?

Or should I switch to Microsoft's alternative?
