I have a Dell Axim x50 and was previously a Palm user, so I can hopefully shed some light. When I was looking to upgrade my PDA, I carefully looked into the Palm Tungsten V and my current Axim model. I personally preferred the Palm OS and the design of the Palm models. The reviews, unfortunately, were not favorable for Palm at the time. There were users who claimed the Tungsten V would frequently crash and the Palm company was experiencing an uncertain future at the time. The Tungsten V also had only 1 memory expansion slot and did not have built in wireless connectivity. I eventually decided to go for an Axim. The Axim was also a cheaper option for me, because Dell had a good sale.
The Axim x50v would have been more expensive, but I did not necessarily need a VGA screen. The disadvantage of the screen would be increased battery consumption. This problem can be remedied by purchasing an extra battery. The PDA dock for the Axim has a slot for charging an extra battery. There are also third-party sellers for larger batteries, but they are large, bulky, and unsightly.
As I look back, I am satisfied with the Axim. There are only a few disadvantages I see at this point. There are fewer software options with Windows Mobile, compared to the Palm OS, although this is changing overall. In addition, the user-interface with Windows Mobile generally requires more taps and is less elegant than that of the Palm OS. Moreover, since the Windows Mobile operating system is bulkier, it consumes more processing power and memory. It is not as responsive as the Palm programs either. Finally, the battery life is shorter.
Although I mentioned a few disadvantages about the Axim, they are not dealbreakers. The availability of software was not a big deal, because I did not plan on purchasing much software and there was adequate freeware for my modest needs. The bulk of the operating system was compensated by a more powerful CPU and two slots for expansion cards. And the battery issue was resolved with the presence of an extra battery as a back-up.
I am not completely sold out to Windows Mobile though. When I make my next purchase, I do not know whether I will stick with Windows Mobile or switch back to the Palm OS. I am nevertheless considering the PDA phones, such as the Treo, as my replacement PDA. Carrying multiple devices (PDA, phone, pager) is a pain in the neck as it is.
