Any document on this subject that fails to mention the Thinkpad Lenovo X2?? series which are epically robust and maintainable and available with reasonably powerful specs didn’t do their research well. (ps hey @comzeradd)
Current ones are also less serviceable than early models (X200, X201, X220, X230 – I had all of these) in favor of thinner design and “modern look” which no one asked for.
The report is based on “best-selling” products, so I guess X2?? didn’t make the cut as not that popular as we may think it is. It also refers to new models, so X280 maybe not that repairable as the legendary X220.
