I have had the Treo 600 for a week now and overall I am satisfied with its performance. However, here are my thoughts.Pro's:1. Small size-this is nice compared to older versions of PDA phones like my old Kyocera 6035.2. MP3 is nice to have-however I haven't used it because the headset adapter is not included.3. Keyboard is nice-takes a little practice to use, but so does graffiti.Cons1. Color screen is too low resolution--needs to be the clarity of aPocket PC devices. Viewing pictures on the Treo 600 is very fuzzy.2. No voice speed dialing-I miss this from my Kyocera 6035 phone. The shortcut dialing feature is too limiting.3. Some interfaces could be better, especially when on an active call.My suggestions to Palm One:1. Either eliminate the camera or make it higher quality-even using it for fun pictures is not good enough.2. Include the headset adapter. Why make it so that you have to order the adapter before you can listen to mp3.3. Needs a replaceable battery. Although the battery life is good, under heavy usage, it is not sufficient.Would I buy it again? Yes, at a $300 price range. To me, it is not worth the retail price of $549.
