I think a huge part of the appeal of Mailbox is it's less than a full-featured project management/GTD tool -- it basically prescribes a certain approach to managing your inbox (do, defer, archive.)

I was a GTD-ish person before Mailbox came along, so I had a system for handling these things, but I know a ton of people who either never made the effort or repeatedly tried and failed to get onto some GTD/task management system; often, I think, due to tyranny-of-choice type issues.

Post-Mailbox, I still manage my commitments in Things, but I manage my "accept queue" (if you will) via Mailbox-- "triage" is really an excellent way to put it. Sometimes the resolution is "I'm too tired to think about this, tell me about it again tomorrow"-- and that works a lot more seamlessly than Boomerang, hitmelater, etc, IMO.

(disclaimer: I have no financial interest in mailbox/orchestra, but I know-- and like-- the team and have given them small amounts of technical advice.)
