I saw that report about 2 weeks ago and for the life of me, I cannot scrounge up enough emotion to give a flip about this test the result or the morons that published the story, ie CNET. Its nothing more than a feel good story for people who are on some quest to prove they "measure up" to what Apple has done with the iphone.
But yeah.....at some point, the resolution accuracy of the test is going to exceed the resolution accuracy of a human, and the results become meaningless.
