moving to jQuery 1.3

I'm finally migrating a site with the ancient jQuery 1.1.4 library (!) to jQuery 1.3. To say I'm excited is a gross understatement. The jQuery team continually blow my mind with smart features and approaches to solve problems. I'm interested in all the features but in particular, I'm anxious to see how the 'no browser sniffing' will work out in the long run. Good stuff.
