I like the idea of keeping the Palm brand. Although I doubt that will happen, I still like the idea a lot.
For one thing, the PDA market right now is basically the iPod touch. Certainly smartphones and tablets are hotter properties, but the former market is saturated (and I wonder if the recent report from WHO will lead to a consumer hysteria backlash against cell phones), and the tablet market is still nascent. PDAs are more compact, anyways.
