@LucyOne - It is probably a wise advise. Wish I have done my homework better before purchasing it. I was really certain that it runs Android
I have another Nook device (glowlight) which is running android and it was quite easy rooting it and installing whatever I wanted on it, and thought I'd be able to do the same for my mom (hence the different device, due to its bigger screen).
Oh well... thank you all, it is much appreciated.
