This is what happens when very smart computer scientists and engineers sit down and build a pure developer's computer from scratch, from the hardware up. It's the most elegant IDE ever invented. It takes a while to get used to it, but once you do, the separation between programmer and computer simply vanishes and you "become" the computer. Describing the experience to a programmer who has never used it is like describing an acid trip to someone who has never done acid: It's always going to sound exaggerated or scary and thus not very interesting. The best IDEs today have incorporated bits and pieces of these ideas but nobody has put it all together in one seamless box the way the Lisp Machines did. I really miss that experience.
