Review: Palm Pre
The Pre has an optional charging accessory called the Touchstone. The Touchstone is a little stand that the Pre can rest on and be charged wirelessly. It uses a technology called inductive charging to send electrical current from a coil located on the charger to the phone. It's awesome technology, but it comes at a price.
The Touchstone charger is an additional $70. In order to use it, you simply plug in the Touchstone and place it on your desk (or nightstand, or wherever). You'll have to peel off the battery cover that comes with the Pre and use the replacement battery cover that comes with the Touchstone. This battery cover is necessary because it has the electrical coil required to transfer the power from the Touchstone to the Pre's battery.
One thing to note. This new backplate has a matte finish, compared to the Pre's glossy finish. It shows off fewer fingerprints, but doesn't perfectly match the texture and finish of the front of the Pre.

Once all that is taken care of, simply place the Pre on top of the Touchstone. You'll feel a pull of magnets. Let the magnets connect, and voila, the Pre is charging. It will rest on the Touchstone charger and you can pull it off quickly at any time if, for example, a call comes in.
The Pre will also mount and hold horizontally on Touchstone, letting the charger double as a video-watching stand. Also, the Pre can sense when it's on the touchstone, and can switch to speaker-phone when placed on it, answer an incoming call when removed from it.
