The market was less established, so there was a lot more experimentation and people just trying to do completely random shit. That's why there are so many cool little tech artifacts from the 60s - 2000s. Now everything is cloud hosted, and web based. We know the form factors: phone, laptop, desktop, tablet. The market's solidified. What will work and what won't is a little more clear, or at the very least that's how people think about it. Nobody's really trying to do some kind of bespoke chip work for a calculator that doubles as a lighter anymore.
