What happened to those phone touchscreen quality tests?

I remember awhile back some MOTO group did a test of several different smartphones and their touchscreen quality and accuracy:


the iphone had the best quality touchscreen, but after that series of tests, nothing seems to have been done since. Are the new flagships phones basically all the same quality now?

I did recently download an app for my sprint gsII and I ran our of fingers to place on the screen to see how many points of contact it could track, so the new phones can do at least 10 it seems, and the line tracking tests are perfectly smooth.
