Definately unfair. When the Vic20 came out in 1980, it was the first computer with color for under $300. Granted anyone buying it for productivity would be disapointed compared to a CP/M system of the era, but those were 10 times (or more) more expensive. The target market was the home, a multipurpose computer that was affordable.
Crap article, crap list. Show me a single system from that era with better specs that was even in the ballpark price range of the Vic. Garbage, they should have listed the Commodore 16, B128, Plus4 or even the Amiga 600 before the Vic20 :-x
