There is a good reason many e-book reader owners are addicted to sites such as MobileRead. You can find all kinds of cool hacks on the site. The latest one allows you to install Android on an external SD card and try it on your Kobo device. The hack is available for Kobo Touch, Glo, and Aura HD. Step by step instructions are available, so you can hack your Kobo faster.
This is a less risky way of playing around with your Kobo software. Keep in mind that you are not going to be able to run the latest version of Android on these devices smoothly. So don’t think this hack will turn your Kobo into a premium, fast Android tablet.
