I just installed the software to manage my 9500iX and I was pleasantly suprised to find that I no longer need a seperate 12V power supply when updating at my desktop. The new units starting with serial no. 22XXXXXXX only need the USB cable to power the unit through the computer.
Also, I see that User Preferences can be set in the software and sent to the unit. This looks to be much easier than scrolling through all those settings on the RD itself.
Just thought I would pass that along just in case anyone missed it.
