Retina Neuroscientist confirms Apple's Retina Display claims

It seems that Apple didn’t lie when claiming, the Retina Display, built-into the iPhone 4, has higher resolution than the human eye can resolve:

Dr. Curcio et. al. calculated 77 cycles/degree or .78 arcminutes/cycle of *retinal* resolution. However, this does not take into account the optics of the system which degrade image quality somewhat giving a commonly accepted resolution of 1 arcminute/cycle.  So, if a normal human eye can discriminate two points separated by 1 arcminute/cycle at a distance of a foot, we should be able to discriminate two points 89 micrometers apart which would work out to about 287 pixels per inch.  Since the iPhone 4G display is comfortably higher than that measure at 326 pixels per inch, I’d find Apple’s claims stand up to what the human eye can perceive.

I urge you to read the entire article by Bryan Jones, he very comprehensibly illustrates the difficulties in measuring these things and shows the differences between the displays of the first generation iPhone, the iPhone 3G, the iPad and the iPhone 4.

Apple's way of slapping Gizmodo in the face

… giving its biggest rival early access to a production unit for review.

And a great review it is, Joshua Topolsky really did a great job.

TUAW writes down MobileMe

… in favour of free services like GMail and Dropbox. Some of the points made are valid and understandable, some are not.

Accepting everything Lauren Hirsch said, I dare her to try to resolve any problem with Google’s support in less than 30 minutes. Because that is what I get with the MobileMe support chat.
