Yeah, really, the inductive charging was nice, but what have been nicer is a port on the bottom of the phone. So... you have your pre. you sit at your desk, phone on the touchstone and you want to put a file, or sync it to your computer... You go, I'll just send it over bluetooth... oh wait, thats not supported. Um, ok, let me get out from under my desk, disconnect the cable from the wall and the back of the touchstone, risk breaking the cover on the pre and hook it up to the computer. Great, now phone is synced, gotta get back under the desk and do it again.
Don't want to do this, wanna keep another cable on hand? OK, pay the extra $15 for the palm specific cable.
I got rid of the pre and touchstone, and just got a hero with a cheap seidio docking station and life has been easier (and much cheaper). Plus, it works with all size batteries due to the awesome design (swivel port on the back allows for bigger phones). I'm using their 3500mAh battery with it and love it. I charge my phone, and gain access to it whenever I want. Plus, with the built in BT transfer, i don't have to be at my computer, or have my phone next to it to send a file. Yesterday, I sent a file to it while I was in the bathroom, computer on the desk in the next room over. Touchstone= overprices and unpractical if you ever sync your phone to a computer.
