Mix08 in LasVegas is opening tonight at 5:30pm GMT (assuming I got my timezone calculations right with daylight savings) - and you can view the keynote live on the site. If that clashes with your commute home, or you're not reading this post immediately - never fear! All the sessions should be available on the Mix site round about 24 hours afterwards.
Apart from the sure-to-be-interesting content on Silverlight 2 (check out the Scott Guthrie .Net Rocks interview on what's happening with the Beijing Olympics, it's about 4 mins in), I know many of you will be interested to hear the news about Internet Explorer 8. Dean Hackamovitch, who runs the IE team will be part of the keynote and giving a sneal peek at some of the new features of IE8.
