Quick update, I decided to stick with my old iPad Pro 9.7 for now. $600 for an iPad Air seems rather steep, and I don't think it would be worth that just for surfing the web and watching videos, especially since I don't watch many videos on an iPad anyway.
What sealed the decision was that Amazon had the Sony X800H 49 Inch 4K HDR TV with an offer to pay it out in 5 months interest free. So I decided I would take that deal since I will use it way more than an iPad, and it will likely last several years longer than an iPad too. The Sony X800H series doesn't have local dimming zones, but I don't think that will be a big issue as I know Sony quality is typically top notch. My current 12 year old Sony TV is still working great, though lacking in modern tech. At any rate, I trust the Sony brand whereas I don't really trust some of the cheaper brands like TCL, Vizio, etc. Besides, the new TV will be a quantum leap up from what I have now and finally get me into the 4K era.
I made the mistake of jumping on the HDTV bandwagon in 2000 and then had to wait a long time before the TV industry adopted, or rather, until the FCC made them adopt to it, several years later. It was a long wait. So with 4K I made myself wait until there was a sufficient amount of streaming in 4K. I still remember my first Sony HDTV. It was crazy expensive, weighed close to 300 lbs because it had the CRT design with thick flat glass, only 32", and was difficult to move around. It was big and bulky! You had to get your buddies to come help if you wanted to move one of those. Kind of cool that even a 65" inch LED TV will weigh only around 50 lbs, and take up hardly any space front to back. A friend bought one like mine right after I did but got a 36" model. When we moved it onto his TV cabinet it took three of us, and then his cabinet broke and collapsed under the weight! We've come a long way since then.
