PalmOS Garnet doesn't
do multitasking, so no surprise. The original Palm OS was based the AMX RTOS from Kadak. AMX has preemptive multitasking, but Palm's license didn't permit them to expose it. Given the limited hardware early Palm devices used, multi-tasking would have been of questionable value in any case.
You can more or less do multi-tasking under Garnet, the same way things like DesqView did it on the PC back when: hook interrupts, time slice, and roll your own memory and process management, and there are a few things that do it, like MP3 players that can play music in the background, but in general, Palm OS is one-thing-at-a-time.
Palm is currently working on Palm OS II (for lack of a better name) that will use an embedded Linux kernel and have a compatibility layer to run existing apps. When it will be out and what it will look like is a matter of intense debate in Palm circles.

Ironically, I have many of the same apps on my windows phone (TCMP, Resco, Google Maps, Mobipocket). It is great that developers are willing to make these cross platform.

Google Maps is a Java applet, and inherently cross-platform. Mobi wants to be a the dominant ebook format, so they have to support as wide a range of viewing devices as they can. TCPMP was intended to bo cross-platform from the start. Resco is going where the money is. So are other developers who develop for both Palm and PocketPC.
