The Retina MPB has opened up a whole world of fonts. It's amazing how much attention I pay to them when I visit websites now.
There is a downside to such a nice screen -- it makes me painfully OCD. On my previous laptop, the screen was such crap that it didn't bother me. On this one, I notice every subtle flaw.
For instance, image retention (which I'm now convinced that after swapping three of these things out eventually affects all of the LG panels used in the MBPR [Samsung panels do not seem to have the issue]).
Then there's the fact that it's just slightly not bright enough for my liking. I find myself hitting the brighten button a lot when it is at max. No matter that my old laptop looks downright dim next to this.
And despite the fact that it is an IPS display, the colors do change quite a bit with viewing angle. A solid white screen kind of shimmers in luminance and tint when moving my head.
And the black level isn't pure black.
And 220ppi isn't quite enough to complete the no-pixel illusion for me.
And the color gamut could be a smidge greater.
It's like the uncanny valley of screens. It's so close to perfect, but not quite there, that it leaves me paying a weird amount of attention to it.
