Barnes and Noble has been making e-readers and tablets since 2009 and people have been rooting the Android operating system ever since. The last e-reader to be released in 2013 only had Android 2.1, so there was not much willingness in the hacker community to unlock the bootloader. The Nook Glowlight Plus on the other hand has Android 4.4, which makes it very compelling to unlock and install apps.
There is currently a thread at the XDA forums with people wanting to root the Nook GlowLight Plus. The e-reader only came out yesterday, so it might be a few weeks before we see any serious movement with being able to root the device.
If a stable rooting method came out that allowed you to install any app you want, at the expense of removing the default e-reading experience would you do it?
