While, yes, most categories will have more than two, many have less than ten. Also note that many of the articles are actually series of products (like Macintosh LC 500 series). I guess the families are okay as are the Motorola/Power PC/Intel chip classifications (that is what's meant by CPU type, right?). Howver, the List of Apple Macintosh models by case type may be more useful than categories since it provides clear groupings and pictures. Though there is a list by CPU type, it is longer and does not rely as heavily on images. I do not oppose turning that into a category.T
