I had a Lisa on my desk in late 1983, along with an Apple II and Apple III and later a PC/XT (not sure if that appeared before they took the Lisa away). The Lisa was for evaluation, so I wrote some reports with it but didn't get to write any code. It was ridiculously expensive, but I could tell that it represented the future of personal computing. Explaining to my friends how it worked was difficult; even the concept of a mouse, much less fonts and a bit-mapped display, was foreign to them. None of my friends even owned any kind PC so they had little to compare my description to.
