I beg to differ, my previous phone was a Palm Pixi + that I used exclusively with a TouchStone charger. I think the charger drew 1amp compared to the .5amps of your typical USB. It probably wasn't good for the battery to get charged so fast, but I had 6 to switch from lol.
Charging in the car was a breeze, everything was hard wired and you simply just stick the phone on the magnetized base and it starts to charge. Though the Pixi+ was a small and light phone, I think Apple can improve the design and make it work with upcoming models.
The Palm/HP Touchstone docks were the only thing that kept me from switching to a new phone for quite some time.
