I took instictive to the gym today so i have some insights "
i have 2500 songs on my n900.

1. CPU usage seems to be quite high, sometimes 100% and its been like this for all my time at the gym, also i had to kill trackerd myself.
2. headset wired play/pause daemon works.
3. unplugging and pausing daemon doesnt work.
4.I didnt like the playlist that instinctive built me on 'Come Clarity' By In Flames. I have loads of metal songs but it often went to my blues or country selection for no reason(eric clapton while running?! plz).
5.My n900 didnt pause for the time i had a call,so i missed it, dont know if it because it lagged so much to pause and start the ringtone or because he just doesnt stop when having a call at the moment.
6.n900 stutters and caughs alot when trying to unlock the screen and do other thing with it(again, could be due to high CPU usage)

Thats It!
I really love the UI, snappy and intuitive.
Also i have a request, PLEASE make a widget for it on the desktop. I just got used to it by now.
Also suggestions: In the upper panel put icons for songs(a note),artists(a person),albums(an album) and playlist(a list?) and in the middle a bigger Back or "Back to main menu" button.

Overall i really like what is going on, Keep It Up!
