There it is again... 
If the description is referring to Commodore 8-bit computers, many were used by business and in education...
To be fair tho, that's the perception now, and it was at the time I remember.
Also, I don't think it's wrong for a generalization..
What can be missed tho, is that you could (and many did) use your "friendly and childish game machine" for business and education.
You could also use your "boring, beige adult box" for games.
My mom frequently did my sister's legal documents on our C64 using the Fleet System 2 Word Processor. Even tho, that C64 was basically a game machine. ;-)
And when the family got a PC with Word Perfect, I can tell you that many a game of Thexder was played on it.. ;-)
I'd maintain that the images of the C64 as game machine and the IBM as a business machine are fair generalizations. Doesn't mean that each can't do a bit of the other.
And personally, I'd generally give the edge to a game machine being more flexible, because moving graphics around and playing sound is a lot of work. ;-)
Now, the Amiga was interesting at the time in that it was "both" from the start. It had the eyes and ears of a game machine with the graphics and sound, but it's mind and heart were equally impressive for business with the memory, multitasking and GUI based OS.
