Liju --

You raise an interesting point about it the market eventually being dominated by cheaper android (or some other OS) devices. I agree that it's unlikely Apple can dominate the market forever and also that consumers' lives will be fundamentally changed by this. I would say that lives have already been changed...I have something called dysgraphia [https://en.wikipedia.org/wiki/Dysgraphia] which makes it very difficult to use a pen to write. Thanks to a succession of technological innovations, I was able to get an education and now a job. It would have been very difficult to do that if I didn't have a laptop!

Thanks for reading and for your comment --
