The article author seems to assume that Apple will steadily increase the performance of part or all of their entire product line in 2021 with Apple Silicon. Since Apple has been doing that with the iPhone for ten years, it’s quite reasonable to assume this will affect their laptop and desktop lines too. The first Apple Silicon release is better than nearly everything available from Intel. That same first release will likely be obsolete by the end of 2021, as Apple advances with M1X or M2. That annual obsolescence may well continue for the next ten years, too. So the used Apple laptop market is going to look a lot more like the used iPhone market - and in the used iPhone market, you get 15% of what you paid, not 85%, because there’s an endless supply of new phones forcing the used market down.
