When the masses decided that a small and light device was worth the extra bucks, Palm found itself with its top-selling handheld. With the introduction of the Palm m500, it's clear that Palm has learned its lesson and is sticking with the successful form factor, while adding a handful of new features to incrementally advance the entire Palm family.
