It now is mostly score on how hard is to unscrew and dismount stuff to make nice photos, and even here can be wrong.

iFixIt for long time is friendly with all leading manufacturers and try not to tell you real repair issues.

Look at this Surface latest shite.

Think product just because designer want it to be thin.

Impossible to get any big parts for repairs (Microsoft services work similar to Apple - replacing products as whole mostly). Company is tracking all suppliers to not allow them to sell any parts on open market, because such approach shorten product life a lot.

Fact what it is easy to unscrew something does not matter anything, unless it is standard modular part you can get from reputable seller in 100% working state.

In reality 50% of reparability score comes from cheap battery replacement availability from third party source (0 here) and spillproof keyboard construction (0 here). As 50% of repairs are exactly battery issues and water damages.

Next 25% is availability of schematics and boardview for this exact model (never mentioned at ifixit, 0 here).

And next 25% is lack of Intel boot guard and full proper protections on all voltage lines, 100% must be on all USB, HDMI and Thunderbolt ports.
