Interesting that the main complaint is that Google does not know how to develop for a competitors platform very well. Have you taken a look at Apple's software on Windows machines? If I had to rely on the reputation of Apple simply by their software on Windows machines then they would be among the worst software companies ever.

Google+, Music, Voice, and Chrome have all been good releases but maybe not earth shattering. So Wave has given them a stench of failure? Really?
