If you have an iPad, Wi-Fi, and $3.99, you can have a much larger and much more functional touchpad for your Mac or PC in no time. Thanks to the multi-touch technology in the iPad, the iPad Touchpad App can do everything a normal touchpad could do, and then some. You can right click, scroll and drag, and do it all however you like. This is a completely customizable app, so you can play around with it quite a bit to get everything sorted out exactly how you like it best. It works in both portrait and landscape modes, too. Mac owners can enjoy full access to pinch, pan, rotate and 3 and 4 finger swipes. It’s all yours from iTunes for $3.99.
