When I purchased the Nook Color this year, my main reason for it was that I have glaucoma and eInk just didn't work for me, because I have to have very dim lighting. Now, I have a jailbroken iPod, so when I heard you could "jailbreak" the Nook, I was all over that.
I was like a kid in a candy store with the apps, downloading any and every (free) thing.
But then something went wrong with my Nook's display and I had to unroot. Now I'm on the newest Nook update and... I have no desire to re-root or run CM7. I think it's because for me, the stock Nook is just fine, even though I love bells and whistles. I can check my email, listen to music, play a jewel-matching game, update Twitter and Facebook with 6sense, look up something on the web, watch a movie and... wait, what was that other thing... oh yeah, read!
So I'm quite happy with my unrooted Nook, and I'm wondering how many others feel the same? For me, I think a "Reader's Tablet' is exactly what I needed.
