I attended the Mix conference this year and was astounded by some of the new technology Microsoft is coming out with.  It was a good networking opportunity to meet PMs from different groups and get some insight to where Microsoft sees the future of the web.  Silverlight stole the show this year and I heard about a new product "Live Mesh" that was coming out soon.  I took a look at Mesh a couple of weeks ago and at first glance it seems to be a synced storage drive.  After diving into the technology a little more, it became apparent to me how impressive this technology really is.  This is a real platform that contains open web standards like REST, RSS, ATOM, JSON and more.  It is a platform to build Software and Services.  It has the capability to wrap existing web applications and take them offline (i.e. It contains a "Mesh Operation Environment - Tiny HTTP Server" that allows offline functionality).  There is always this pressing concern in the IT world as to which technology to use.  This is an exciting time to be a developer!
