My thoughts? Stop complaining if you don't have first hand experience with the retina MacBook Pro machines.
I'm still with this guy. I've been using Retinas at 1920x1200 resolution since they were introduced. It was bad under Lion, it was mostly OK under Mountain Lion, and under Mavericks (and throughout its betas), I've had zero problems.
I personally think that they shouldn't have put in scaled resolution. Everything looks the best and performs the best when it is in "Best for retina" since it doesn't have to do additional interpolation and filtering operations unlike scaled ones. I understand a lot of people want more "screen space", but until the GPUs provide hardware support for scaling from such a high resolution, there will always be a performance impact, thus the scrolling lag. Keep it at "Best for retina" and it'll be fine.![]()
The arrogance in this paragraph is super obnoxious. You like it best that way, and you want to impose your personal preference on everyone else? A lot of us are perfectly happy with things at max resolution and aren't having any performance problems that bother us.
