They have core boot, which is a big plus, but the hardware itself is not open source.

You can also buy it second hand or get an older version for less money and upgrade later.

The upgradability and reparability is also a cost saving factor on the longer run. I broke the screen once and instead of buying a new laptop or have a costly repair, I just got a replacement for 200 bucks and fixed it easily myself.

Out of the box battery was not great for the 11th gen, but with the correct settings I get 0.4-0.5% drain/h in standby.
