It's really interesting to see the super-knee jerk reaction here when the article itself even says that most of the features made their way into gmail. (I was a heavy inbox user, and i am happy with the stuff that made it's way into gmail). Outside of some of the bundling features, i'm curious what actual difference people are complaining about here.
> Outside of bundling Bundling is the main development that Inbox brought to the table.

Three things are highlighted:
Extraction of info from items and display (now in gmail)
Bundles (some made it into gmail)
Reminders, assists, and Snooze (now mostly in gmail)
So i'm not sure i'd agree with you here, but i definitely would agree that of the big three, bundling made it in the least :)
