One-to-Many
Here's a couple cool toys from Microsoft that allow you to use one computer with multiple users. I imagine this would be great in the classroom, but I'll be there are some other cool uses too...
The Multipoint Mouse SDK allows you to use multiple pointing devices on one desktop. This would be a great way to develop for multitouch environments, without having to invest in multitouch development workstations.
And Microsoft's new Multipoint Server allows a single Windows Server to function as a complete desktop for multiple users.
Windows Phone 7 Series
So the cat is slowly climbing out of the bag on Windows Phone 7 Series. I think I'm allowed to say that I've seen it, and that its awesome. The initial set of information was announced at MWC, to pretty rave reviews.
I'm new to blogging about Microsoft, so I won't say any more, for fear of messing up. Follow CKindel on Twitter, and plan to be at MIX 2010 if you're interested in learning more about this pretty revolutionary step in mobile device interaction.
