If you weren't able to get into Tech-Ed and wanted to, some overflow slots opened up. You'll have full access to the whole conference but will have to sit in overflow seating (read: a different room watching on video) for the keynote address. Still, not bad to be able to get into this otherwise sold out (11,000 attendees!) conference. Just go to http://www.microsoft.com/events/teched2005/default.mspx
to see if slots are still available (they are as of this posting).
