i would advise others not to upgrade to the new itunes 7 if you are not so keen on the news features. my reason? it's still very very buggy!

my music tracks are skipping like mad, as though i'm playing a scratched CD. and while playing songs through itunes, other applications that produces sounds will also interfere with itunes (eg. WLM, yahoo messenger, windows media player).

apparently i'm not the only one experiencing this problem, and it's not windows only. mac users have reportedly have problems as well.

some people reported that newly downloaded podcasts are unplayable when transfered to the ipod. some even bricked their ipod while updating. (thankfully it didn't happen to me).

did any of you guys experienced problems as well?

Yes. DO NOT download and install iTunes 7; there's a huge thread with over 20,000 views already at Apple's forums with scores of other people experiencing similar issues. Had to revert to iTunes 6.0.4.2 but you'll have to uninstall iTunes 7 (if you've already installed it), and re-import your music library as follows:

In Windows to do the same look under
My Documents -> My Music -> iTunes
Move the files iTunes Music Library.xml and iTunes Music Library.itl to the Desktop (Do this before re-installing iTunes 6)
Run iTunes
File -> Import
Select the iTunes Music Library which you copied from your desktop
Wait while the files are imported.

Why all Mac users doesn't experience lagging issues but Windows users does?

Also, this doesn't seem to affect everyone....

yesss u go to Mac Studio low yat they got sell Price Rm 1100++ for 8GB

Sadly, no foobar for mac osx yet

I just use Amazon for my album art.  Sometimes people post 500x500 images from the iTunes Store as well, so it's a good resource.  Updated and now my iPod Video doesn't have any strange syncing issues

nah, I'm using PB G4, 10.4.7 and upgraded to iTunes 7.0.1. the same problem i've been having is iTunes now won't recognise or play other MP3 files which is not part of the library (say, if it wasn't burned from CD or downloaded from iTunes Store). so annoying. 7.0.1 haven't sort that one yet.
