The iPod is a great counter-example: there have been times Apple was selling 4 different lines of iPod at a time, most of which came in an array of colors. The apple watch basically comes in two sizes with an array of 'colors' (metals) and watchbands.

The difference between that and the history is that each iPod has a clear niche. The problem Apple was having with such a selection of products is that it was hard to figure out which one should be purchased as they didn't have clear, differentiating roles.
