I've disliked iTunes for quite some time. I tried it when I first got my iPod (I'm still running a 4th gen. black and white screen 20 gig that I wish would die so I could justify getting a new player) and back then it's sluggishness was ridiculous, and not all of my music was uniform so I hated all the time it spent converting wmas into mp3s and adding them to the iTunes music folder so I ended up with all sorts of duplicates and what not. (I now no longer have wmas but it annoyed me back then.)
I still think that it draws far too much from your system resources, and yes it's no problem on modern systems, but I still think that that is no reason to make it bloated. I also hate how frequently it updates and that there is no way to patch it, you simply have to download the entire 70 Mb executable for every update, rather than a small 1-2 Mb patch. I hate that it has 4 background processes for one program. And probably my biggest issue with it comes from my job. I do software maintenance and upgrading on a college campus, and a faculty member requests iTunes so we have to install it on all 800 machines we manage. I have spent countless hours fighting with iTunes to deploy it to these machines, and have simply found no way to do it in a simple manner like almost all of our other 60 software packages work. It irritates me to no end that a media player takes more time to update and deploy than it does to update and deploy math, physics, statistics, and a myriad of other much more powerful applications.
