How do you know that it is a real 5100? It's not turned on. If it was so mint, then why didn't he turn it on to prove it? Why is he outside? Because the paint was wet? If he was an IBM worker, or even a computer buff, he would know about he 5100. I think that with all the truth he probably told mixed with a little bit of cool physics theories makes an intriguing and desireably believable story.
