Yes because as we all know email is exclusively the domain of the young, idle Bourgeoisie

Your absolutely right. The last 14 years of iPhones, Google Search, Gmail, Maps, Facebook, Social Networking, the very site you are using right now... can all be summed up by "a bunch of twenty-something hipsters from California high-fiving each other."

I read the original link, and watched the video on that page, and had pretty much the same reaction as the parent commenter. If this service is perfectly clear to you, then please elaborate for the rest of us.

It appears to be sorting and arranging various bits of data. The examples shown include messages, and a flight reservation. What all kinds of data bits DO integrate? Does this read my email (or replace it)? Does this read (or replace) the news feeds of my social networking accounts? Where did it get that flight itinerary? Why is everyone in this video talking a selfie every two seconds, is Inbox sharing or managing photos for you?

I think this supposed to be an improved version of Google Keep, perhaps with some hooks into Gmail and your phone's camera. But all I have to go by is a few paragraph of fluff, and a 60-second video of young people staring down at their phones. Feel free to fill in the blanks, if you picked up some more solid information that we're missing.

Relevant doesn't necessarily mean requires actions. I average around 100-150 relevant work emails on a typical day (can also be 20), and plenty of them are ones that I only need to glance at for 5 seconds - some that I don't even need to read but need in my inbox for potentially looking up later.

I work in marketing for PC hardware, so very different sort of workflow to coding.

This is exactly what they want to do. Ads embedded in streams/feeds have proven to be the most profitable monetization strategy on mobile, and Google's missing the party on that one. It's an attempt to take one of their powerful, existing products and turn it into a mobile feed.
