I think they might still make non-phone pdas. They are a good place to try new technology, and they still produce a profit. It's just not a growth market. But we'll see. I'm converted myself to the smartphone idea. But I think I probably prefer smartphones that are more like power-pdas with a phone in them.
I'd like to see a nice one from Palm that looks kind of like this (it's the one Michael Mace pointed out on his blog)...

Very nice. Closed it looks like a regular phone. Open it's a full pda.
