I set up a smart folder as an inbox in OS X's Mail client. That smart folder only shows me unread email. The traditional inbox is so cluttered and broken. Everything gets the same weighted priority in my inbox and all based on time. That doesn't work. Categorizations (labels)seems like a great way for me to use my inbox the same way as a GTD app. That's huge for me. I get lost in my email and over-run pretty quickly, often missing things I need to do, or revisit. I think Mailbox is on to something here. People use their inbox as a todo list already, labels just makes it easier to pull off. It's a pretty genius move.
