ASUS working on Tegra 4 powered slate with a Retina display-like screen
Not much more information can be gleaned from the trip through the GFX site. We can add that the slate will be running Android 4.2.2 and there is a good possibility that we will see this tablet at the IFA show in Berlin next month. Besides the tablet seen on the GFX site, there is talk that ASUS might end up being the brand behind a refreshed version of the Google Nexus 10, taking over for Samsung.
By the way, for those who don't know the story, you might wonder how Apple could call the fourth-generation iPad a Retina display with a pixel density less than the 300ppi requirement that Apple came up with. Remember, this is Apple's own term. The answer is that the Apple iPhone is typically held 12 inches to 15 inches away from your face while the iPad is held further back at an average of 15 inches to 18 inches. This difference allowed Apple to reduce the requirements for tablets to 240ppi. Thus, the 264ppi found on that version of the iPad qualifies it as a Retina display.
