It is a toy for you. It's also a toy for me. But, it's a easy way to check email and the web for my wife, a way to learn letters and numbers for my 3 year old, and a video player for long car trips for my son. To me, that's the most incredible thing about the iPad and perhaps a factor in its success: the incredible versatility and extensibility you can get from a small flat screen with one button.
