In its current form, sure I agree. But to me thinking that we will just see a future of miniaturized TVs is like thinking we would just keep making faster horses instead of shifting the paradigm. As the smartphone was the nexus for multiple technologies, so too are AR headsets. They are getting smaller and lighter and will become less obtrusive and with more intuitive user interfaces and interaction modalities, just as has been done with computers taking their myriad forms. I'd much prefer a private, hands free mode of interacting with a computer in public, not to mention the AR potential. Misplaced your keys? Well, they were last seen by your headset on your desk ten minutes ago.
