Both deserve alot of credit for their developments and their work on further extending the Desktop.
Now, what would be nice to see would be a download made available for the CTP, TAP & TBT groups on Connect that contained the Sidebar so we could actually TEST it. You know that's one of the things that caused so much attention to be placed on Longhorn/Vista and why there are so many imitators right now (i.e. DesktopSidebar, SmartBarXP, etc).
BTW, Sean - if you're reading this: what happened to the DMC Geek Dinner at Crossroads? Never heard anything more about it...
