If they do not replace everything, there is a possibility that they damaged other hardware that could fault down the line. Since most repairs are covered under limited warranties, if they don't repair or replace those parts, they could be on the hook for liability for those faults, and would have to repair it again at their own expense.
Nope, warranty isn't an issue in this situation as its been voided. So that entire quote is void. They have no risk of being on the hook for anything. Leaving nothing but the actual cost of the repair which falls 100% on the owner solely. Even if it required replacing everything, its on his dime not theirs, and they don't have the liability risk.
And all of this is outside of the stupidity of releasing a product that supposedly can't be repaired in the first place.
Apple sell the retina screens for a 15 inch mac book for around $1300. I can't imagine how much they are selling the iMac pro screen for but I'd assume it's more than $2,500. Logic board another $1,500. PSU, $250? Then labour. In the car world if it costs 80% of the value or more, it's a write off.
Ridiculous prices or not, he destroyed 2 major components of the computer.
In the car world its a total loss because your carrier owes you only up to the value of the vehicle. However even if your repair bill for your car exceeds the value of the car itself, nothing stops you from footing the bill and having it repaired anyway if you decided you wanted to do so. You just cannot force your insurance carrier to pay above the cost of the vehicle itself.
Some of these comparisons are garbage man.
