I got a $25 Fire TV Stick and plugged it into the back of my TV. I push 1 button and everything powers on and Netflix, Hulu, or Disney+ launch automatically. Any other service is a couple button presses away. All in 4k. (Well Hulu is upscaled)

I never have to leave my sofa. I don't have to dick around with plugging and unplugging my PC. No keyboards to manage. No OS or software to keep updated.

Your solution is easier than some other options but I'll stick with mine.

I too wish I could have a laggy experience with a bad interface requiring me to pull out my phone and search for which of the several services I pay for have a particular piece of content on my phone then slowly navigate to that service then try to enter the search term character by character by moving a little cursor to each individual character with my remote.

Then have a firmware update ad some advertising to the experience.

Sure beats my experience of pulling out my 12 oz keyboard plus touchpad bluetooth keyboard connected to a real PC.

The Roku stick is even better because it isn't inherently locked down by Amazon's ecosystem. Far more services that are effortless to install.
