Yeah, exactly, I don't understand why they don't make "Photos" a folder in Google Drive and vice-versa. Subfolders can be albums, so when you upload something from your phone to G+ it also shows up on Google Drive, and when you drag a photo in your Photos folder it gets uploaded to your G+ account.
I don't really care that much, though, since there's no Drive client for linux (how hard can it be to port the thing?).
It's actually pretty well done, I used to use it til I moved to ownCloud. Interestingly it's more stable than the official client on my Mac, on Ubuntu 12.04
It's nice that there's a third party option (yay for open APIs) but it's pretty weird that Google still hasn't bothered to make a Linux Drive client themselves. This is basically the only reason I'm still using Dropbox primarily, though I'll probably start moving some files to Drive when the bonus space I got from their college competition thing expires.
