I think its disingenuous to imply that because someone doesn't notice or care about the increased PPI of a laptop, they don't appreciate the small joys of life.
ok replace 'the small joys' with 'some small joys' the point is still the same.
It's similar to what John Carmack said when he was testing out the Rift VR Headset with Rage.
He said he was fascinated in just looking at the bricks in the walls and being able to 'look around' objects in the world, which gave him a new appreciation for all of the art assets that are for 99% of people just a blur as they run past shooting monsters.
I find myself a million times more "productive" in Sublime Text 2 with a "light" theme (Soda Light) than previously when it had a dark theme (the default one). I do look for substance, but we are all machines and can't fight over our limitations. My eye thanks me when it can visually see an "orange" function instead of having to look for a "black" (i.e. misspelled) fuction in code. It's not my fault - eyes appreciate semantically color-coded (or typeface-coded) blocks of code/article/etc (my last sentence is poorly phrased, as a non-English it's hard to articulate what I want to say but I'm sure you understand what I tried to say).
Catching resolutions up to print DPI is not "style", it purely a quantitative exercise.
The screen is the only component of computer hardware that we use at full capacity all of the time. It is much more important to get displays up to print resolution than a small clock speed increase.
