I liked Apple's approach when the iPhone 4 and MacBook Pro 2012 came out. Adding @2x bitmaps was easy enough for developers, and the transition was quick and painless.
Since then, however, Apple's UI has (regrettably) become less about pixel-perfect bitmaps and more about black typography on white roundrects, and almost all Macs run at a scaled resolution by default, which is then typically used to display web-based apps that support fractional scaling.
I really think that Windows' approach has aged much better. Kudos to Microsoft. We could have our cake and eat it too if Apple sold Macs with slightly higher-resolution displays, and also a 5K 27" display because other manufacturers can't be bothered.
