I had one once. I honestly thought it was awful.I respect that your experiences may have been different but I found it painfully slow and bulky. The detachable battery broke as well and had to be held in place by tape. I opened it once and it looked like a bunch of bits arranged to look like a laptop. Anyone who has seen the elegant neatness of the inside of a Mac will understand what I mean.
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.
Replying on my X220, which is my go-to device for writing, non-graphic intensive gaming, and general web use. It's light enough for my needs, and is built like a tank. Plus, I cannot stand more modern laptop keyboards, and I'm hooked on pointing sticks. I've got my desktop for anything that really needs processing power.
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.
The parts are easily available, cheap, and virtually everything is user replaceable. It's great.
