What does this have to do with anything? The iMac is also shrinking in marketshare. The last reported data says it’s less than 5% of annual Mac shipments, a completely different story from 1999 or even 2009.
And it is reflected in the product line, a thing has barely been updated in five years other than the chip, and they have completely abandoned the 27 inch more pro focused model, likely because it was probably A lower profit margin item that still likely sold in the less than 5% region by the time it was discontinued.
I was explaining why I bought a Mac Mini, a desktop, and not a laptop, and that I am not "...significantly more tech savvy, and are very unlikely to not be able to understand the difference between an M6 and an M5 Pro, and not know which one is right for them." Oh, and did I mention how much I hate laptops?
