You didnt read what I had posted like, on the first page. The pixel density is doubled in the same amount of screen space. Therefore, you can't even see aliasing unless you took a magnifying glass (even then you'd just see the pixels themselves, not the aliasing).
Apple's iPad Air has 3.1 million pixels - wowzers!
Lets see the pixel density, it comes to a total of,
wait,
"2048-by-1536 resolution at 264 pixels per inch (ppi)."
what? 264ppi? Thats terrible. This thing costs more than my phone and my phone has 441ppi.
Surely the retina display is better!
"2048-by-1536 resolution at 326 pixels per inch (ppi)"
Seriously? only 326 pixels? Still more less than 441 and - you guessed it - still more expensive.
Retina displays are stuff. My phone which is only 1920x1080 has a higher pixel density and costs less - oh, and it looks better.
Oh and that last part about a magnifying glass is also bullstuff.
441ppi you can see pixels at 7.8"
