I still have a 2012 MacBook Pro as my main laptop :(
The hardware lasts, but the software compatibility stops way too quickly. So for people who aren't willing to install linux, etc it isn't known for longevity.
I fired up a 15" 2008 MBP to run some non-CS Photoshop and you know, it works great as long as I'm not using the Internet! It's a solid machine, and I miss it.
Now typing on my work machine, an 8GB M1 13" MBP. I wouldn't say I've been blown away by this and it's probably because I need 16GB to deal with Chrome and its zombie Electrons.
