The recent tracking issue with Apple has come handy the iPad users. The location t=kept in your iTunes assists MobileMe to track your lost device/tablet. You do have to have a free account, then with any computer you can check the location, make a message display and even remotely wipe it. You can also make it perform sounds to warn whoever has the device/tablet, the owner does know the location.
This may cause Blackberry to attack Apple as Blackberry offers a service called Blackberry Protect which does the same actions, the back up and restore options are not included with the iPad.
