Perhaps with DOS?

I don't need to imagine it, I've used 4/8GB early Airs, netbooks, slow Gateways and Dells. Turtles. I don't want to optimize my RAM. If something runs away, I'll kill it. I need more RAM. What you are saying is romantic in principle, and I don't disagree with the principle, but that's a dream and we need more RAM. I can subsist on rice and beans and tofu, but I don't want to.
