Are you interested in developing for Windows 7? I bet you are. I know I am. So perhaps you would like (OK, I'm quite sure you would like) the Windows Summit. It's a virtual event hosted at http://www.microsoft.com/windows/windows-summit/ and it claims of itself:
Windows Summit 2010 is designed for people who engineer and test Windows 7
PCs, devices, and software. Three technical tracks are offered to show how to
best use Windows 7 and Internet Explorer, helping you build great solutions and
gain a competitive edge.
It's free (you just have to register) and features about a dozen talks in each of three tracks. The Software track will release June 16th, so you can mark your calendars for then and amuse yourself in the meantime with the Device and System tracks. The Software talks will cover multi touch, ribbon, IE9, Windows Error Reporting, sensors and location, power awareness, background activities (that's services and scheduled tasks) and performance. All good stuff.
I'll report back in mid June when I can actually play the sessions and look at the downloads, but it seems to me it's going to be a very good resource.
