I’ve come to think of Mailbox as being designed to complement what you’re already using on your tablet or desktop. It’s an app that helps you sort out the unimportant stuff when you check your phone at a café or in line at the grocery store so that you only see what’s important later.
This is how I use Mailbox, too. It’s a truly mobile-specific take on what an email app can and should be — it’s specific and it’s opinionated.
