When you're doing graphics work, you often find yourself looking *that* closely at your display.
Really? Your eyesight is good enough to detect pixels clearly enough to make a difference in an image that has been rasterized at 3840x2400 & then interpolated down & displayed on a 15" 2880x1800 retina screen? Sure you can...
If the pixels on your display are visible, you're sitting too close to it.
Ah, so my being able to see the pixels of a 24" 1920x1200 screen is "sitting too close" but you can see interpolated pixels in a retina display.
Personally, I wear glasses when staring at a monitor
So do I now that age has hardened my lenses, but mine don't give me super telescopic vision the way you claim to have with yours.
you don't understand the implementation of the technology you are using
Snort, sure sport.
Clearly, you've never done any real graphics-intensive work
Ah, who's this attempting to draw conclusions and failing?
When did I change my position? I did not. I did, however, clarify that position
Righto, you just led with the equivalent of "I don't hit women" leaving out "but I do make sure my wife stays in line". The "clarification" doesn't change the position fundamentally, no, no, not at all...
In parting, because we're clearly done here, your incoherency & refusal to admit that your any part of position is wrong (ex: your aftermarket SATA drive is clearly slower than the recent rMBP's PCI flash) proves to me that my judgement of your character was well founded.
You believe that you're always right, any who disagree with you must be wrong so instances where you've been proven wrong fall into your blind spot so they can be safely ignored. Go back to using Windows, you're a bad fit with the Mac crowd.
