Nice machine but 1400€ while the laptop in the article is $200. So you could replace it 6 times and still come out ahead... and drive more than 1 external display.
Also, I am not sure that the ram or storage won't become limiting within these 10 years, e.g. media is only getting larger (120GB+ for baldur's gate 3), LLMs,... . On a non-mac you can simply grab a 2TB ssd for like $100 and in 8 years can probably replace it with like 8 or 16TB for about the same price.
Again, perfectly nice, quiet, fast machine with a decent display, but soldered stuff sucks. If that were not the case, I would consider upgrading to it from my current 5 year old machine (also 14" 2k HDR ips screen, 16GB ram and above mentioned 2TB ssd upgrade). However, paying 2000€ just to match the ram and storage of my 5 year old laptop is definitely off-putting and you also don't get OS upgrades for the full 10 years, right?
Fwiw my 2012 mbp still runs. Takes in plenty of dust working outside and on account of the plastic hinge turning brittle and falling apart years ago. Once every two years I will open her up and blow her clean again. Thats about all the maintenance she needs today. Ironically it has somewhat stronger specs than gps new m1 air, considering I also have 16gb memory, but then 1.5tb of storage and 2 operating systems.
