For those palm treo 650 on up users, if you need a hotsync/charger that you can take with you when you travel this is defintely the one to have.  Its a no-brainer type of accessory and it DOES do both charge and hotsync your palm treo device on your desktop or laptop computer.  I got it because I travel a lot and don't like disconnecting the cable from my desktop just to take it with me every time I head out of town.  That is the convience of having such a good accessory as this combo.  I would have given it a full 5 stars accept that it did not have a hotsync button directly on the cable itself.  You have to go directly to your device and use the hotsync application on it in order to do the hotsync; which is ok but having the button on the cable itself would have been a plus.  Other than that This product is excellent.
