Wow, I'm a bit numb. I just delivered the book’s last chapter (on WinFx I mean .NET 3.0) to O’Reilly.
I’m going to go sit down, relax with a non-technical book for a bit, then jump in to polishing up the book’s introduction section. After that it’s time to get cracking on consolidating input from our technical reviewers and polishing things up they’ve pointed out.
There’s light at the end of the tunnel, and it’s not a train!
