Ok, we already knew most of the reasons it would suck from the release announcement, but this...
I literally can't believe even HP can launch this sort of turd.The Slate 7's display is a 7-inch number that is 600 pixels wide and 1024 pixels tall, a ratio of 1:7.066. But the actual real-world dimensions of the Slate 7's display are 4.4375" (112.7 mm) wide and 6.0625" (154 mm) tall, giving an aspect ratio of 1:7.636.
What this works out to is a screen that's been stretched by 4% along the vertical axis. Instead of filling the space with more pixels (or, you know, just making the device fit the 5.86" inch-tall screen that the 4.4375" width would dictate at that resolution), the screen seems to have been stretched to fit the available space.
