Is it better than Apple though?

He says 80% will be repairable by customers or channel partners.

Apple is probably well above that already. They already offer repair service for their phones, tablets and laptops.

Also, when I stopped paying attention to thinkpads (due to them botching a warranty repair) ~100% were repairable. You could get schematic diagrams, etc.

Dropping that to 80% is a huge regression.
