Microsoft’s Courier booklet device looks quite slick indeed in a collection of leaked photos Gizmodo posted today. The images are clearly from a document that explains Courier’s interface. These aren’t the first pictures that have been leaked of the device, but they provide the most complete guide to what it will be capable of. It’s clear from the photos of the Courier that Microsoft intends it to serve multiple purposes, and that the device is not limited to being an e-book reader or standard tablet. If Apple’s rumored tablet comes to fruition, it could also face significant competition from the gadget.

Gizmodo supplies some interesting specs for the device:

The dual 7-inch (or so) screens are multitouch, and designed for writing, flicking and drawing with a stylus, in addition to fingers. They’re connected by a hinge that holds a single iPhone-esque home button. Statuses, like wireless signal and battery life, are displayed along the rim of one of the screens. On the back cover is a camera, and it might charge through an inductive pad, like the Palm Touchstone charging dock for Pre.

It’s worth taking a tour of the photo gallery and considering the possibilities that are evident from the user interface. Check the shots out here, and the leaked video here. Microsoft’s Professional Developer Conference (PDC) is coming up in mid-November, and there are supposed to be some big announcements. Could Courier be among them?
