For those of you considering upgrading to Windows 8 don't unless there is some other reason you need to like using the EP121 as a iPad style tablet. I checked about the state of Intel's support for the Intel HD Graphics contained in the ASUS EP121 and they are already dropping support. This for a graphics card in a slate pc that hasn't even been for sales for close to 2 years yet from one of their top hardware customers (ASUS) and their top software customer (Microsoft)!!! The Intel HD Graphics card itself probably is barely 2 years old now. It seems Windows 7 will get better support than Windows 8 unless you are running on hardware that is shipping with Windows 8 to store soon. That means any tablet or laptop from 2011 is getting short changed in Windows 8. At anyrate for those that need a digitally signed driver that supports a version of openGL newer than 1.1 from the 1990s update your MS WDDM 1.1 Intel HD Graphics driver by update hardware driver, uncheck compatible with this hardware, browser for driver, manually choose driver, choose Intel as the manufacturer, and chose Intel HD Graphics as the device. This will get you a version of the driver by Intel certified by Microsoft from 2011 that supports openGL 2.1.
