And given the PDC presentation release, you can go to http://microsoft.sitestream.com/PDC05/ and search for InfoPath and get the OFF306 and OFF319 sessions. Offer good for a limited time.
An additional bit I forgot about: if you haven't read Steven Sinofsky's PDC keynote, put some time aside and surf over to
http://www.microsoft.com/presspass/exec/ssinofsky/09-14PDC2005.mspx . Notice how often Steven touches on InfoPath technology within Office 12. InfoPath technology and scenarios
are integrated into other Office products (Outlook, Word, Excel, PowerPoint, and Access) and the more you know InfoPath the more you're going to be able to get out of Office 12.
