I thought I'd summarize the key points that I came away with from this morning's PDC keynote. Today's session was focused on infrastructure, so nothing yet on Windows 7 or .NET Framework 4.0; that's on tap for tomorrow. If you want to catch the entire keynote (it ran about 1:45), it's available on-demand now at the PDC site. I tuned in to the live-blogging session as well, which was kind of fun, but it had a higher noise ratio than I'd hoped (comments on red shoes, etc. - you'll have to watch the keynote to get the references though!). There's a bit of a delay in the keynote feed too, so some of the live blog comments were 'ahead' making it a little puzzling at first. You can tap into the blog feed from Mary Jo Foley's blog tomorrow (or replay today's) if you like.
