"Inbox functions very much more like a ToDo list than it does an email client."

That's exciting to hear, since I've recently started turning Mailbox into a combination email client/to-do list/evernote replacement. I've found that having all those concerns in different apps meant that I never wound up using any of them often enough.

The shared concern seems to be the triaging of things that hit an "inbox" of sorts. Email hits the literal inbox, to do's hit my "stuff I need to do" buffer, and notes hit my "categorize these notes later" buffer (I compulsively note things down for later). Ultimately triaging things as their hit the Mailbox inbox is most effective for me, so I've turned it into my single source of triaging.

I'll definitely give this a shot if/when I ever get an invite ...
