The current Apple TV 4K is great.  I would take advantage of the sale price if you want one.  Most TVs don’t support latest capabilities anyhow.  

I have the new M1 Macbook Air. I bought Aldente Pro and tested it against Apple’s own battery optimization algorithms. In my experience using Aldente Pro resulted in more battery cycles. I highly recommend sticking with what Apple provides.  Apple has fine tuned their algorithms.

I’ve had both and prefer Android for the phone because of Google’s superior voice recognition and processing.  If you want to use voice in the car, Siri is not your answer, or Alexa for that matter.  I have a Macbook Air M1, iPad 1.29, but don’t miss the iPhone in the least.
