One of my favorite PC / IOS apps is called Reflector. As a teacher I wanted to project my ipad onto my whiteboard.Â The best way: Wirelessly is Reflector. With Reflector you can AirPlay/mirror your iPhone 4S, iPad 2 or the new iPad to any Mac or PC, wirelessly.Â You can also record your ipad. It is really easy, and you can try it for free.
Decide to purchase and the cost is less than $15, cheaper than the projector cable you would have to buy from Apple.
Here is a great video created on how Reflector.
