Interesting article by Joel Spolsky:
In the second stage, everybody bought PCs for their desks, and suddenly, programmers could poke text anywhere on the screen wily-nily, anywhere they wanted, any time they wanted, and you could actually read every keystroke from the users as they typed, so you could make a nice fast application that didn’t have to wait for you to hit SEND before the CPU could get involved. So, for example, you could make a word processor that automatically wrapped, moving a word down to the next line when the current line filled up. Right away. Oh my god. You can do that?
I think he takes an opportunity (later in the article) to kick Google in the shins for no good reason, but otherwise it’s a very interesting bit.
