You're right, in their mobile phone dept. they've come a long way since the first iPhone which started with a 2 - the iPhone 6+ has a 7

Their tablets are bad, looks like all of them got a 2: https://www.ifixit.com/tablet-repairability

There is no simple overview for laptops/PCs so I randomly picked some:

>iMac 27" Retina 5K >5/10

(a slightly different version got the same score: https://www.ifixit.com/Teardown/iMac+Intel+27-Inch+EMC+2639+... )

>MacBook Retina 2015 15" (not OP's 13") >1/10

>iMac 21.5" EMC 2638 >2/10

>MacBook Pro 13" Retina late 2012 >2/10

>MacBook Air 13" Mid 2011 >4/10

So I change my above statement: Their current mobile phones and their desktop machines are alright to good in repairability scores, tablets and laptops are bad
