Not that I have the totals, but when I was going through the factory tour the 19' and 25' Safari units were the most popular (in whatever config selected base Safari, CCD or SE). Since the FB units came out in a 27' and they are avail in Classic, I'm not sure those numbers are still true.
Computers manufactured by companies such as IBM, Compaq and millions of others are by far the most popular with about 70 million machines in use worldwide. Macintosh fans note that cockroaches are far more numerous than humans and that numbers alone do not denote a higher life form. -NY Times 11/91
