Steve Ballmer might have no idea what's going on with the Microsoft Courier tablet, but a new set of documents leaked to Gizmodo certainly suggests the product is more than just a couplevideos the boss-man hasn't seen. The images detail the Courier's unique user interface, which draws on everything from multitouch gestures to pen-based handwriting recognition. The heart of the interface appears to be the Smart Agenda, pictured above, which pulls together all your disparate content like calendar entries, emails, and to-dos into one unified starting place, described as "Cliff Notes" to the Pagestream "novel." The journal itself appears to be searchable by all kinds of data, including time, location, and tags, and it's all accessed by a special multi-button pen. There's also a camera and an offhand mention of "boos and subscriptions," so it sounds like whoever was dreaming this all up considered using the Courier as an ebook reader as well -- which would be totally sweet, given the types of annotations you could do. Of course, none of this is real yet, but we're hoping against hope -- please, Mr. Steve, make our holiday dreams come true?
