I buy used paperback books even when I could buy them new. I feel no guilt that none of my money is going to the author.

I just did it for the first time yesterday with an old Kindle I had lying around. It was super easy with this website: https://kindlemodding.org/

I haven’t experience this myself but I’ve read that some newer TV’s are forcing you to connect to the internet before you can do anything else.

This finding is becoming less important by the year. It’s been quite a while since you could easily buy an HD TV - they’re all 4K, even the small ones.
