This may be a case of following the data with disregard to the dynamics. 1. In the beginning there was G Mail and there where two camps(roughly): a. Those who made heavy use of e-mail, and where "adapted" to the user interface. b. Those who had problems with the UI(replying to all their emails, etc...) Of those two camps: those in camp `a` where unlikely to switch. That would have interfered with their workflow. Those in camp `b`, not all switched because people resist change. Change takes energy. 2. Then there was `Inbox` Now, there is a subset of camp `b` which has adapted its workflow to use Inbox. The most satisfied ones are here complaining :). They don't want to go back to G mail, but will be forced to. The questions I would ask, if I were responsible for shutting down Inbox, are: * How many people were leaving inbox for G mail? * Why?
