I'm heading off to Mix06 tomorrow. My first time to Las Vegas...
Other Microsoft attendees have started making their way down too: PeteL, Visual Web Developer Design View Tester; Cyra Richardson, Program Manager at IE; 'Vibro' Architect Evangelist and the Keith Smith form the ASP.NET team.
Lots of cool sessions planned there this week by some very interesting speakers.
I'll be staying at The Venetion (here's a bird's eye view).
If you're going at want to meet up, let me know!
