"Dreams come true, and I’m thrilled to share this one with you. Using the $15 Reflection App on an Apple computer, it’s now possible to MIRROR the screen of an iPad2 or iPhone4S right on your screen. This essentially makes your Apple computer function like an AppleTV for iOS mirroring, except you don’t need to purchase and install a $99 AppleTV with a HDMI cable. This is HUGE for teachers and anyone else needing to share an iPad screen with students over a projector."
