"Everyone" has palm pilots already. WinCE-based PocketPCs haven't made much of a dent in the marketplace. There is also a very large developer community for palm apps, and they're widely deployed in corporations.
I am not sure that the existance of a large developer community has much bearing on the suitability of Palm as an encrypting phone platform. As for the hardware, it simply is underpowered. You can spend man-months trying to fight the current underpowered Palm platform or you can use the sufficiently-resourced PowerPC platform. Since I don't believe that there is a requirement for the feature to operate on a device already in the user's possession, I know what my choice would be. YMMV.
If you're assuming users will buy a dedicated device *and* put linux on it, that's reasonable (or sell pre-packaged systems). Otherwise, you also need to develop for WinCE on the PocketPC.
The OS is really of secondary or tertiary concern here. The more important question is which (if any) handheld hardware supports full-duplex audio. Do we know for fact that the lack of full duplex audio support on the VoIP handheld demo is due to lack of support in the HW or could it be a lack of support in the WinCE OS? --Lucky
