I don't think you read his post.
I read his post. I just disagree. Even my laptop from 3 years ago has more power than any tablet or phone out there. I know that myself and most of the people that I know prefer a full computing experience to that offered by a touch screen device. Tablets are great for a lot of things, they also are not ideal for a lot more. As far a as portability goes, I prefer my Macbook Air to the iPad (in a perfect world Apple would release an Air with a touchscreen,)
