I enjoyed the article, but I just can't completely agree. The microwave is seen as essential because it gives us humans such a valuable asset - time. Our time is hugely valuable. I don't see tablets, iPad or other, having that same impact. Sure they have some great qualities and they can make some tasks easier and more convinient, but not significiantly quicker. That doesn't mean they're not going to successful of course, I just don't seem them becoming ubiquitous.
