I've also been wondering if I should try 1.1
I know that updates are generally a good thing, but in this case I've adopted an "If it isn't broken, don't fix it" approach to 1.1 1.03 is working just fine for me.
Installing 1.1 would be a good idea for those who want to watch rentals on their iPod though but since I have a pokey 256k DSL link I won't be doing that anytime soon 😛
