: I hope you as an "optician" go out of business real soon now. When you say that you know the human eye cannot resolve anything over a HD screen, the only thing you show is that you're a f*cking moron. Really. You're arguing against reality.
I can trivially
see the difference between that 2560x1700 screen and some random 1080p "HD" screen. It's as simple as just making text smaller, although you can actually see it in just about anything.
Seriously, why do people continue to make this totally idiotic argument that is so trivially
shown to be total and utter crap? And why do you then try to back it up by lying about your profession? Because if you are really
an optician, I fear for your customers, and you should be sued out of the profession for being incompetent.
If you cannot afford the thing yourself, just go into an Apple store and look at he 13" rMBP and make the text really small. Just compare it to the non-retina machines. Because it's that
Although maybe your
eyes are so crap that you cannot tell the difference, and you're just in denial about your own physical deficiencies. If so, just trust me, most of the rest of humanity is better endowed in that department than you are.
