I am long overdue for a PDA upgrade and had my mind set on the Palm Tx, which is wifi and seemed to have all the features I need at a reasonable price. Then I found that it has no voice recording capability, which is a total deal breaker since I sometimes need to record important interviews! Is there any microphone accessory available for this device? Otherwise, will I have to resort to a Pocket PC device? How much of a hassle is this for a Mac user?
