On the flipside, there were the days of the Power Macintosh 6100, 7500, 8500, 9600, and other models. It’s very easy to look up different models using these names, and there was also logic to the naming scheme, but it was confusing for people new to Macs to figure out, and this was back in the 1990s when there were still large amounts of people in the developed world who never owned a personal computer.

Once Steve Jobs returned, he replaced the product numbering scheme with a quadrant: consumer desktop (iMac), consumer laptop (iBook), high-end desktop (Power Mac), and high-end laptop (PowerBook). The high-end models had a suffix (G3, G4, G5), but it got confusing with all the variants (e.g., Wallsteeet vs Lombard vs Pismo PowerBook G3, various revisions of Titanium and Aluminum PowerBook G4, etc.)
