I edited my comment to clarify, however to do so here: what I mean is they didn't adopt the touchscreen paradigms, such as onscreen keyboards. The Pre required you to use the hardware keyboard, and had no virtual keyboard functionality built in. It lead to some odd interaction patterns. My recollection - which could be wrong - is that Palm did pivot to pure multi-touch interactions but it was never released, as HP largely gave up on the phone market by that time.
