Well for those with poor vision like me it is a blessing to have my computer use the 70 inch model as a monitor. I do not need or want a smart TV but that is about all they make. I think Apple should just make their TV as an iPad and use their Track Pad as the interface. I have used a TV as a monitor for about five years, started with 55 inch now up to 70 inch, getting old sucks {:<).
Well, I’m 73, and don’t have the best eyesight in the world, but I made my living in front of a computer for years, and I am most comfortable with a keyboard, and a mouse.
I have and Ipad, but I don’t like it much, I prefer having a mouse/keyboard.
I took two years of typing in high school, and therefore am a trained “touch” typist, and I hate those “on-screen” keyboards, as well as the “mushy” keyboards now found on laptops. I need some “travel” and “click” to my keys.
I haven’t watched broadcast television in almost two years, and find that I’m happier for it.
Good luck with your 70-inch “monitor”.
