I dislike Apple, but this is the way future will like. AR (and maybe VR, but who knows) will definitely be amazing in a decade or so. BUT I think some people will still stick to smartphones, especially ones who don't want to spend their whole day with technology and social media.
I am definitely buying an AR headset, as long as it's affordable and can replace at least half of the tasks I do on my computer/phone. The AR device with Windows 11 and computing power of standard computer would be just fucking amazing, and I wouldn't go back.
