I've recently purchased the NC - and in the process, read a bunch of reviews. I thought I'd list the link to reviews for others doing research on the device. My filter was to only place reviews where the author apeared to have had at minimum a few days testing before publishing - I ignored rethose where the author only had a few hours hands on.
There are probably tons of other I missed - feel free to add others are you find them.
