Remote control iPad

I seem to remember that if the device is Jailbroken there are some free VNC servers for iPhone. Otherwise just buy one I suppose at least I wasn't able to find one free of charge.

If you jailbreak your device, you can install Veency (search Cydia for it) and then use any VNC client to remote-control your iPad.

That said, the experience isn't all that great since the iPad isn't particularly fast at delivering the screen's contents, and things are a bit strange controlling your iPad (which is inherently touch-based) with your mouse.

That said, it's free. Changes are good, though, that your other, more expensive options are probably better. Put it this way: I installed it, played with it, and then have barely used it since. The experience isn't good enough for me. (Plus, I'd rather save the iPad's precious resources for actual apps.)
