I just got back from my local suburban BestBuy big box store. The PDA displays have been nearly swept away. The space nearly taken over by mp3 players.
There are now only 4 PDA's available in the store (and only 3 on display): 2 HP PPC models (one of those was wireless) and 2 Palm models - Zire 72 and Tungsten E. And it looked like they would have really liked that space to display even more mp3 players.
I asked the clerk and he said that PDA's: "just don't sell." He suggested I try the internet to buy.
It is not looking hopeful.
If any of you are in an electronics store perhaps you can stop by the PDA display - then report back here on what you find.
