At one point, 64kb was useful for something. There is an infinite number of uses for 64kb. Its only the decision being made that its not useful any more that makes it so - the users change, not the computers. I still break out my 8-bit machines now and then for some fun, localized, minimal computing. Its amazing how much you can get done in a little bit of RAM, but the 'amazing' is just the result of an arbitrary decision, nothing more.
