Don't get me wrong, I use and love a lot of terminal-based software. But from an information density perspective, my computer can display seven 80 column terminals over a hundred rows tall at once. Also, my keyboard is not awful, so I can actually do a lot of typing very quickly. For the occasions where I need a mouse or graphics they're readily available.
So echoes of, but not at all constrained like, computers from that era.
