2. Cover flow view is slow. When Steve Jobs demoed it, it flows very smoothly. On my PC (P4 2.6GHz HT, 1GB ram), iTunes only start loading the pictures when I'm looking at it, meaning that the picture would be empty at first, then I can see iTunes loading up the pictures. Scrolling is very slow since iTunes is loading the pictures as I move. It won't pre-load anything if I stay at one spot. Once all the album arts are loaded, scrolling is then very smooth. Problem is, once I close iTunes, and re-open it again, it repeats the same thing. Why can't it store a cache somewhere instead of loading the album arts again and again?
4. Scrolling through library still produces high CPU load (50%-100%).
I would say that these two things are due to your videocard memory/drivers. The pc seems to be good enough (heck! i'm on a P4 1.5Ghz! ) to not have such problems.

3. iTunes7 encoded AAC, although gapless with iTunes, apparently is not gapless with foobar. I probably have to use gapkiller to froce gapless playback. Weird since Nero encoded AAC is gapless with foobar, but might not be gapless with iTunes.
If you haven't yet read about the Ipod gets gapless playback thread, i advance you that it is using its own tagging scheme to mark the gapless tracks. This means A) it is not recognizing nero aac way. B) others don't recognice iTunes' way. Both quite logical. (ok, they could have known about nero's way)
