Well, Steve Jobs has some explaining to do.

1) It's pretty slow, I have over 15000 songs in it (all off MY OWN CD's).

2) When importing my own files it lacks a progress indicator, even the most basic shareware crap has a progress indicator

3) In true Apple style you CAN NOT maximise the application, I'm left with a window in the middle of my screen and can't utilize my desktop the way I want to.

4) Visualizations are VERY SLOW, even on my Dual Xeon workstation it stutters a lot, I also don't seem able to select different visualizations...

In it's defence, the search option is very fast compared to WMP9.

I'll try it out a few more days but my first impressions are just that it's a nice try but is far behind what WMP9 and Musicmatch can do.
