I dunno. I feel dropbox has been getting less and less usable as their UI tries to get further away from the very light wrapper around windows explorer(or whatever file explorer your OS of choice uses).

I really just wanted it to be a folder that exists on all my computers. That's it. Now when I ask it to open the dropbox folder it stays within it's own application window and attempts to recreate windows explorer, but without all the features of windows explorer and tons of gunk I don't want.

This seems to be a problem of both the "lets push our userbase into patterns that work for us rather than them" and "Hey I'm a UI designer so I have design me some UIs, and I'll never stop, even though the UI is correct, I'll keep changing it forever!"
