The parts are easily available, cheap, and virtually everything is user replaceable. It's great.
I enjoy how my X220 really is a laptop of Theseus; over the years I've replaced everything except the LCD rear cover, bezel, hinges, and base. The biggest problem is getting decent batteries.
I get your point but this is pretty irrelevant to many people who want the machine to work. Function over form or some such. I'd rather have a durable, repairable machine than a "pretty" machine that allows me virtually 0 upgrades or I have to eat the cost of hundreds of dollars every time I have to send it to Apple care.
The thonkpads I have are fairly repairable, durable, and fast. Yes, they're bulky but weight is generally not an issue for me.
I think most people who write these comments are just comparing a 2002 thinkpad to 2023 mac.
Also the CPU and RAM were soldered on it, which makes it even less repairable.
The bonus was that for the same budget as standard Macbook Pros at work, I got 32GB RAM and the top i7 plus a thunderbolt dock.
