It seems I do not really have to hope my vendor will provide an Android update for my phone, as Google distributes most cool new stuff using the app ecosystem. As with Inbox, I think Google is finally generating sufficient pressure on developers and businesses to use meta-data for their mails and websites. I appreciate that. If their text parser for stuff like locations and times works for non-english texts, I'll be a super happy user!
The flip-side to this is that the Android versions of these apps aren't getting anymore love. Messages is now Hangouts, Browser is now Chrome, Calender is now GCal. I heard that the Gmail app is going to start allowing Yahoo email accounts too. Android is much more locked down than it once was.
