Dvorak wrote a few mentions of the Amiga in his columns in PC Magazine as well over the years. The one I recall most clearly is a column in which he's listing what hardware PC users should have on hand to avoid downtime due to failures. The Amiga came up when he was talking about keyboards. For PC users, he recommended they have one in case of failure and goes on to mention that the single most reliable keyboard he ever used was his Amiga (a 1000 I believe).
