This is a very cool concept—a rethinking of email by Tobias van Schneider. I must say, I would definitely like a mail app that looked like this—and had these kinds of features. This is roughly, anyway, how I organize my email as it is. (I use Sparrow when I can.) I especially like the management of attachments; this would be killer for me at work, where I am stuck with Outlook. Mr. van Schneider’s broader point is a good one: when we spend so much time each day on email, why does the experience suck so much?
