And those are valid points.
Most of my 2600 "life" was spent playing on a 19" Magnavox in my bedroom. I played it some as an adult after marrying and having kids, but obviously not as much. Now that my kids are getting close to grown (and divorced now), I'm savoring playing again. Perhaps it's something to do with all those years of staring at a 19" screen.
Funny though, because there are some TV shows that are broadcast in SD, and I see how crappy they look on an HD TV. I don't remember seeing them looking like that, but obviously the TV brings out things that were limited on an old TV. Perhaps if I played the Atari on an old TV again, I couldn't go back.
