I'm quite happy with my Nook HD+. For the money, I think it's a better product than any out there (that's why I bought it of course).
But their marketing absolutely stinks! I get emails occasionally from Amazon with all kinds of great deals like 99 cent apps or books or videos and I've bought several that I use on my rooted Nook.
B&N on the other hand, sends me emails EVERYDAY advertising the latest $14.99 ebook or wanting to sell me some toys. I often get emails of coupons from them as well that say "**NOOK devices and NOOK books excluded". Well, that excludes me altogether.
The problem's not with the Nooks, it's with their eco-system that they're apparently unwilling to change.
