A new set of documents leaked to Gizmodo show off the Courier’s user interface, which uses everything from multitouch gestures to pen-based handwriting. Looks like the core of the interface is the Smart Agenda, which pulls all your content together like calendar entries, emails, etc in one starting place, described as “Cliff Notes” to the Pagestream “novel.”

The journal looks like it’s searchable in many ways, by time, location, and tags, and it’s all accessed by a multi-button pen. It also features a camera and there’s mention of “books and subscriptions,” so you may be able to use the Courier as an ebook reader as well. None of this is official, but man does it look sweet.

Microsoft’s Courier tablet took us all by surprise. Now an internal video has surfaced showing how Microsoft thinks we’ll use Courier, giving us an overview of the interface and more of Courier’s features. At the core of the Courier is the “infinite journal”, a journal/scrapbook that is endless, presumably bound only by storage. The journal can be published online, and it’s able to be downloaded in three formats: a Courier file, Powerpoint or PDF. There’s also a library where things like subscriptions, notebooks and apps, are stored.

It also shows some more traditional elements like a smart agenda, more defined folder system, universal search and multi-page web browsing. Nothing about viewing content, like watching movies, reading books etc. It looks like Courier is all about creating and writing with a pen, which is not what we are used to, especially when you think about the Apple tablet.

According to a recent report from Gizmodo on Tuesday, Microsoft is confirming rumors that it actually does have a new dual-screen tablet in the works, codenamed Courier. According to the article and a short demo video, the Courier is a real thing and is more like a “booklet” than a tablet as it folds together and has two interactive touch screens side-by-side with loads of fast functionality.

The project has apparently been kept under pretty tight wraps with very few, both inside and outside of Microsoft, with knowledge about it. In fact, rumors are that the team working on the project, led by J. Allard (a designer involved in the Zune and the Xbox) has been kept away from the main Redmond campus to help keep it secret.
