answer:I guess a lot depends on your lifestyle and what you expect to get out of your phone. For example, if you travel around the world a lot, I would recommend looking at the Palm-based Treo worldphone models (such as the 680 and the 650) since these are the ones that have quad-band as a feature—which is critical if you’re away from North America. I know there are also Treo worldphone models that use Win Mobile, but I’ve not looked at those at all, because the thought of adjusting to Win Mobile after more than 6 years using the Palm OS fills me with dread. The 680 in particular is interesting for me because it doesn’t have an antenna sticking out the top. The only thing that’s stopping me from upgrading from my current Treo 600 to the 680 is the fact that the latter still doesn’t have wi-fi (actually none of the Treo phones do, as far as I know), although it does have Bluetooth. I’m a lot less familiar with the product roadmap for the Palm OS, so I’m afraid I can’t give you any meaningful feedback there.
