I think it is just to simply show what OS can have the most applications open at the sime time and still be usable. Symbian appears to be the OS to beat when it comes to multitasking stability. I have run instances of Quake and Quake 2 at the same time for active multitasking and S60 v3 handles that well. Since those are not native apps, they continue to run "live" in the background without pausing to the menu or anything from what I can tell. Same thing with the N900 just and a prettier scale on our mobile pc.
