InSync? Not first party, but I heard everywhere it's really good.

I used InSync with a mounted drive. I rebooted and it ran before the drive mounted and deleted my entire online google drive contents and then deleted the local files when the drive mounted.

The google UI is such garbage that you can't undelete 1000s of files so I had to write a script against it's API that ran for a few days restoring everything. Sucked.

I've been using it for the past year. Works perfectly find, no complaints. Definitely worth the $40CAD I paid,even if I plan to move away from Google Drive in the near future

Ubuntu supports Google Drive out of the box, it appears in the file manager. Probably it's Gnome doing the actual work, I haven't really bothered to learn it well.

Was not aware of this, interesting

If you want client, not necessarily sync, GNOME has it built-in. It'll mount your Drive using FUSE.

Why would you run Linux and use Google Drive? If you don't care about FAAN(M)G reading your data and activity, Windows is simpler and has better compatibility.

Consider that I may use a tool like Google Drive for a subset of data that I don't feel is particularly sensitive or identifying in nature

You can't use Google Drive without providing identifying information (a phone number or a payment card) to Google.

EncFS over GDrive/Dropbox is great!
