Not much has changed in email but Mochila ($tba) seeks to shake things up a bit. Centered around iOS, Mochila is a simple email client that uses pinching, swiping, shaking and different kinds of interaction. In this preview You can see how it looks when the user has swiped down and "Create New Message" appears. You can also easily pinch anywhere on the screen and a search field will appear- handy. The service is scheduled to be launched near the end of 2012 with a web app, desktop app and an iPhone app. For you early adapters they are already taking beta sign-ups.
