I has the same 3 window all the time.
1) media player witch plays local music while i move, or netradia when i'm at work
2) xchat IRC client when i'm on the move (otherwise it runs from my PC/laptop)
3) Easy debian

Inside easy debian i also run some more apps.

Sometimes i go above 3 window, but it is rare (mostly all i do is open conky, xterm -> root -> kill hildon-xxx process witch keeps CPU usage at 100% for minutes, pointlessly or makes the desktop unresponsive for minutes).


The only one feature what i realy miss from the task manager is the ability to drag and drop opened window into an order what i want (A similar function what windows 7 offers on the taskbar.). It simply irritates me if i can't reach this permanent 3 opened window from the exact same locations all the time, while from my laptop at work i always find that 8 permanently opened apps from the same places on the taskbar.
