I remember reading in a Amiga magazine (around 1994-1995) that the US and Canada had about the same number of Amigas even though the US had 10 X the population. Apparently they were much more popular up north.
That seems about right. Whenever I read comments about the Amiga not being popular in North America I always wonder "what the heck?" and have to check to see where the author is from (usually the USA). Here in Ontario, Canada my friends and I had Amigas. There were several stores nearby that sold them, too, including at least one in the local mall. I worked in a K-Mart store (a retail chain now gone from Canada) in 1988 that sold Amigas and Amiga software in the Electronics Department.
The CD32 was even around (although I only saw one or two) - but by 1994 the Amiga was fading from Canada.
So blanket statements that the Amiga didn't do well in North America really should be edited to "The Amiga didn't do well in the USA". Here in Canada it didn't do too badly --- nowhere near as well as the C64, but I don't think that was the case anywhere.
Commodore was also way more prevalent in schools here than Apple was (the reverse seems to have been true in the USA).
