Palm Touchstone is a exclusive Palm Pre accessory which allows WIRELESS charging via induction process. It’s design and color matches the style of the Palm Pre.
Although charging wirelessly sounds great, but it would take nearly 4 hours to full charge a dead battery, which is more than what the wired charger would take. Also, keep in mind that if you buy Palm Touchstone, you will also need to buy the Palm Pre back cover to make it work.
