Same. I have an old school 2013 MBA and a fresh MBP for work and I don’t really notice the difference.
Of course I can _see_ the difference. The MBP looks really nice. But when I sit down to code or watch a movie on the MBA, I have pretty much the same experience as I do on my work machine.
I use a setup with multiple screens, some of them Retina, some of them not (the lack of high resolution external displays is a pity...).
The difference in resolution is immediately obvious, but once I start working I forget that the displays have a different resolution.
Things like aspect ratio are much more important, and I think that 3:2 is the best aspect ratio for work. 16:9 and even 16:10 has always felt a bit cramped in the vertical, 3:2 feels perfect.
