livramax, you just struck home with the second link! I was really confused as to which CM release to make use of.
That said, should I go for the latest M release or a previous one? If anyone is happy/unhappy with a certain build, please say so
Edit: I was contemplating whether my dad would benefit from a rooted device. I installed XBMC on my laptop last night and I think that would be mandatory now... all that TV! Also whatever software I use, it has to be stable because my dad cannot troubleshoot it. Stable rooted rom appeals more and more to me, provided I can circumvent the device's (apparent) tendency to wipe itself if it detects changes in the /system folder.
Edit2: The Nook arrived yesterday (£129 from Blackwell's). Superb build quality indeed! Crappy stock software, tho. I've got CM11 M10 running on it - good stuff. I tried turning ART on but it just made the tablet sluggish in my case. For now - dalvik all the way. I'll continue testing it for a while to make sure my dad won't encounter any kinks.
