When my first Macbook lasted for more than 3 or 4 years I was surprised that I was upgrading before it died. I went through many upgrades with almost zero issues(one HDD failure, one battery failure). I still have a 2012 Macbook Pro that I've since installed Linux on.
When I bought the first touchbar Macbook (late 2015?) I spent around $6k maxing out the options, and I was surprised at how totally trash it was. Hardware QC issues were shocking: particles under the screen from manufacturing, keys stuck within the first hour of usage, external monitor issues, touchbar issues...
I haven't bought a laptop since.
They don't, but the difference is that Windows users generally don't know or care about processor generations. In contrast, it's common for Mac users to know they have an "old" Intel-based Pro, an M1 Air, etc., and to use that knowledge to help determine when it might be time to upgrade.
You can test this by asking Windows users what CPU they have. For the few who know and who have an Intel CPU, you can ask what their Brand Modifier¹ (i3/i5/i7) is. If they know that, you can ask what the 5-digit number following the Brand Modifier is — the first two digits are the Generation Indicator¹. I'd be surprised if more than 0.01% of Windows users know this.
¹ Intel's name
My interpretation while watching the event is that this is a company persuading x86 holdouts to upgrade to Apple Silicon, and maybe some M1 users as well.
Not at all. I've worked with FANG developers with brand new M1 MBPs that had no idea what 'm1' meant until something broke.
