I just wish that iTunes would allow different controls for different media. I want to organize my movies myself, while I'd like to let iTunes take care of pretty much everything else. It's a nuisance to have to remember to turn on and off the "have iTunes organize my media" depending on whether I'm adding movies or other stuff.
Also, I'd love to be able to have a central iTunes library that could be shared with all computers, such that I could choose to sync things from both the central shared library and the local library on my computer when syncing with my iPad/iPod. Instead, to the best of my knowledge, anything I want to sync with my iPad/iPod I have to pull into my local iTunes library.
With regards to iTunes 11 release, while I do understand the frustration coming from the fact that it was delayed at the end of October, the reality is that Apple has a track record of almost always releasing at the end of a month that they've said they would be releasing a piece of software in. It's frustrating, true. But if you just expect that "released in November" really means "released on Novemeber 30", then you avoid all the worry about it not being released before. And, hey, if they choose to release it on the 20th, or something, then it's a pleasant surprise. But, really, given Apple's track record with release schedules, it doesn't make sense to be so negative at this point.
