Keep in mind Apple was dispersed across a multitude of confusing and overlapping products, from computers, to PDAs, cameras, scanners, printers (laser and inkjet), application software, servers, things made by Apple, and things that only got Apple's label, and so on. A common complaint was that not even Apple employees could figure out which Mac was more powerful just from the model number.
Jobs simplified the lineup - two sets of laptops, two sets of desktops, one professional, one personal. This shut down a significant part of the operations across the board.
