At my small startup we tried using Google Drive as a Dropbox replacement a year or two ago. We are paying for Google apps so it made sense to try they're Dropbox-like service, and it had some seeming advantages too. We found it to be a lot less reliable than Dropbox in most senses. UI is worse, error handling is poor, you may easily end up losing data. Not worth it. Now we pay for Google apps for gmail, and for Dropbox for file sharing. Which btw has become a lot better now that there is cloud sync available in the pro subscription (not only in the business subscription), they raised the price from $10 to $12, but I'm so happy that I have been able to recover some much needed disk space in a convenient way!

I agree with the issues with the Mac OS client burning too much CPU/battery, I've learned to live with that as an inconvenience, since otherwise, it works great by fulfilling the top priority you want in a service like this: it is reliable.
