To my credit, I was referring then to the iTunes music store, and not the iTunes library/application, which has gotten a lot better since the awful crash prone monstrosity that shipped with my first iPod. So yes, growth - but growth from Apple, who improved their software.
I actually still don't use iTunes, to be honest - I just don't feel comfortable posting which pirateware that I do use.
I get my videos from Mininova.org. Just search for "iPod" and you'll find movies, tv shows, and music videos, all formatted for your tiny low-res iPod's screen!
(I'm kind of a snob as I watch movies on my Palm T|X which is twice the resolution of the iPod on a screen that is 60% larger that costs $100 less and also is a computer, ebook reader, email client, web surfer, date book, games machine, and also plays mp3s.
I love my Palm T|X. It's replaced my laptop. My iPod is nice for when I go for a walk or something and don't mind carrying something small and easy to manipulate with one hand while it's still in my pocket. </aside>)
