I was using this device for last couple months. It's by far the best tablet I've ever used. It feels great when you hold it and thank god for better aspect ratio! (compared to N7). I also have N10, but never really liked it, it was quite cumbersome to hold it. N9 feels much better in hands.

The thing I loved the most though was keyboard cover. It's narrow but you get used to it very fast. Typing on it was such a pleasure! I was not allowed to travel with this device but I could easily see myself just taking N9 instead of laptop for short trips.
