Tech Wisdom is to blame
Speaking for myself, when younger I wanted a PC that could run a small country. Was I running a small country? No. But I wanted to have the power to. As you get older you realize that most tasks don't require a lot of power, and while a 16-core desktop may render HD video in record time it isn't any faster at getting my email or looking up a recipe online. And you still have to wait for it to boot up. A tablet on the other hand can be with me in the garage so I can watch that instructional video about how to repair my car while I do the repair. Or I can read my email while smoking a cigar in the cool of the evening on my back porch. The older one gets the more downtime one has and the more a tablet makes sense.
