I have a student who just got an iPad for Christmas. He was deeply frustrated and upset to hear that it did not have the same operating system as his Windows laptop (and no pen). He didn't know that Apple made a different operating system and had never heard of the Macintosh, though he had heard of the iPhone. Not having heard of the Macintosh, I can understand, but in this modern multiple cell phone operating systems world do people really not understand that iPads will be different than Windows PCs?
