It's true for all brands, but especially true for Lenovo - the enterprise machines are nothing like the consumer-grade crap.

A lot of people will incorrectly shorten it, and even pass it on with the error. But the advice isn't to get a Lenovo; it's to get a Thinkpad. Do not get an IdeaPad, or whatever other names they use for the cheap crap. Get a Thinkpad.

It's a similar story with HP's Omen vs Elitebook and Dell's Inspiron/Vostro vs Latitude. The enterprise line is very different in every way.

This report draws no distinction between them, as evidenced in the one section that lists models.

As for repairability, I've always found it easy to find the HMM for Thinkpads. My experience is limited, but they've also been relatively easy to disassemble and reassemble.
