Apple's laptops sales are decreasing.
Right now. But that’s because the M1 and M2 Mac sold like hot cakes and we’re at a quiet stop in the product timeline. They pick right back up when the new models drop.
And most Mac users can't tell the differences between Intel, the M chips, AMD or whatever.
This is silly. The M1 models were leaps and bounds better than the Intel predecessors. That’s not all due to the ARM chip, but list a “MacBook Air 2020” for sale and watch the Mac heads stumble over each other to ask “intel or m1”.
They just know that there's a pretty apple on the back of their laptop and that's why they buy it.
People generally tend to stick to one ecosystem because of lock in effects, such as investment in apps etc, but that’s equally true in the windows world. I’m not sure I would classify Mac users on the whole as tech illiterate though. Most know exactly what they are getting and why.
And they are also A LOT of Mac users that just want a decent Unix machine and sturdy, capable hardware.
