BTW, good luck convincing anyone in the Early Intel Macs forum that non-Retina machines are obsolete. Keeping them going and relevant is kind of our thing here
Moreover, Retina-branded and True Tone-branded screens are engineered, contractually, to be impossible to replace outside of Apple (due to Apple’s strict contract restrictions on the supplier of those screens from selling those parts to anyone other than Apple and, more recently, having the displays cryptographically matched/locked to the logic board). And once Apple eighty-sixes a Retina-based or True Tone-based product, the utility of that product will be obsoleted not by its diminished functionality (hardly!), but by the overt anti-competition of being unable to replace that screen. This probably constitutes a litigously unchallenged monopoly.
Put another way: once the next-gen displays to replace Retina and True Tone emerge in the Apple line-up, those displays will be obsoleted, but still perfectly usable,
so long as it doesn’t break. Fortunately, for pre-Retina displays, many, if not most
can be replaced with OEM supplier parts still available for sale.
As for
usability or
usefulness, if one can easily see what one is working on, whatever that might be, then that screen ain’t “obsolete” by any measure.
