I have the Nook-branded Vara stylus. It was a pain to get; on order for weeks and they only shipped us (I work there) a few. Our first order sold out in a few days, and we only received six this time around.
It works great from what I've seen on a Nook Tablet, and works decently well on my Nook Color. Even though the specs list the capacitive rubber tip, the packaging states that it is for the SimpleTouch only.
I think corporate just messed up because the SimpleTouch doesn't even use a capacitive touchscreen (or a traditional touchscreen at all for that matter) and it seems obvious that it was released for the tablets.
Lists for $19.95
