It appears the first documented case of someone actually switching from a Mac to a PC is none other than Jerry Seinfeld. If you watched Seinfeld at all, you know that Jerry was an avid Mac fanboi and Apple products were never far from his side. This switch-a-roo kills the thought of "once you Mac you never back". Funny thing is, Jerry Seinfeld apparently had the change of heart after participating in Microsoft's Mojave Experiment. The fact he was paid $10 million had absolutely nothing to with it.
