I've never really changed my stance on what is retro even as the years go by. NES and SNES and Sega games from that era. I could see maybe lumping N64/PS1 into the category, though. The point about PC games contributing to a cut off seems like a fair one. I'm not sure the last time I saw a pay phone, and it has to be 20 years since I actually last used one. 1.5 billion more people have access to cell phones than toilets. If pushed to decide, a lot of people who have both would probably choose phones. If you ever have a problem, someone will probably let you borrow one, unless the problem is lack of service in the area, but businesses still generally use landlines that they will probably let you use. Unless they are jerks. I remember once I was running through the rain after my car had broken down, and the gas station refused to let me use a phone.
