Prey for iPad and iPod Touch would be a great
My cousin just lost her ipod touch 2 weeks ago. I wish prey were installed...
It would be hard, apple doesn't allow full system access (which prey needs) unless you jailbreak your device. You can also sign-up for the MobileMe fildmyiphone service, it gives you some basic tools.
So, many people lost their iPods. Adding them to the list of compatible devices would be a lifesaver for many.
i vote for that too
