Absolutely not. With Google, you're guaranteed quite a few things.
1. Lack of updates. Nexus 7 issue.
2. No support. Or read as "Community driven support" as in go to a forum and beg.
3. Beta = not even alpha.
4. Expected to pay retail production price for buggy crap.
5. Have to complain on HN or twitter to get any sort of response.
6. Every device chatters to home base constantly.
7. Updates end up downgrading features.
8. No safe fail-over when services halt (mailbox death with merge tool).
I'm truly wondering whether you mean that Google usually makes high quality, or that they usually screw stuff up. I'm assuming the latter, because it's what I agree with (anyone ever used Maps or, say, Android <5?) but maybe I'm just weird that way.
