Here's two graphs charting the ascendancy of windows mobile.
That big spike in 2000 was the tech bubble. Palm will never have it as good as they had it then.
As you can see, WM passed POS shipments in 2004, and currently ships almost twice as many units as POS.
You can also see that it has been PPC's which has been growing the market for a while now, and Palm is slowly sinking away, even in absolute numbers. These graph (of Canalys numbers largely)
include Treo's BTW.
BTW, new Palms are horribly unstable, much more so than new Pocketpc's.
