Gmail was and is a slam dunk.

The google browser so far seems like a flop, but the jury is still out.

The last I used Google docs, it was still having trouble reading a docx file correctly.

I would consider switching to a Google OS if I had some assurance it would run all of my professional graphics, video and audio production programs ("for Windows") without a hitch. Then, there would need to be a cost incentive (as in free, or a fraction of the cost of a Windows OS).

It all comes down to price and compatibility.
