Wait? Whom has these expectations? I presumed most in the tech industry scoff at anything Google launches, point at Google Graveyard or at all the failures they've been through.
Seriously: aside from search, ads and android, what product has Google developed ever that is of high quality and meeting the high quality? Maybe maps at some point? Gmail, maybe? Google docs? For each and every google product, I can name two competitors that meet much higher expectations of engineering.
