The most obvious feature Google should have invested 5,000 man hours in: making Wave seamless in GMail as a standard. If you are talking to another GMail user, Wave should be automatically turned on for that message. I do not understand why this wasn't deathly obvious to them from the day that they announced Wave at Google IO 2009.

It could be that there were turf wars involved in this. It is not inconceivable for the Gmail product manager to not want Wave integrated. People switching to Wave could mean the end of his clout in company.

I don't know enough about internal Google to really say whether this is probable or not, but I've worked for companies where that would have been the case.

I'd be willing to accept that if we were talking about Microsoft. I thought Google was still better than that?

They were too busy botching the Buzz rollout.

One reason this might not have happened is because you don't fuck with gmail. That's 180 million users right there. Repeat: you don't fuck with gmail. (But I would have liked the wave/gmail rollout, yes.)
