What I do is answer or dial the phone, put it on speakerphone, then you use one of the "hard" buttons like calendar or home to get to the palm functions. So I can look up other phone #s or check meeting notes. I just got a bluetooth earpiece and am learning to use that, I imagine it will also allow phone operation along with palm operations.

You cannot surf the internet and use palm functions at the same time. In that way the palm OS is much more single threaded than the windows. It is also more dependent on the touch screen than windows mobile phones.

Go try one at a sprint store and see if they can demo for you. Remember the Centro is exactly the same functions / sw ( 99% at least), so if you demo a treo 755 you will get the same experience.
