They did not "do it right" if you're a heavy Gmail user. List of things that suck or are missing from the Mail.app Gmail experience (in no particular order): 1) 1-click archiving 2) stars 3) labels 4) priority inbox 5) aliases 6) spam marking 7) filtering 8) searching through message archives (messages not downloaded to iOS device) 9) drafts 10) proper conversation threading There are probably a lot more. Those ones came to mind in <30 seconds. I sincerely hope Sparrow for iOS will address these issues so that I can get push notifications without missing Gmail's best features.
