The US customers should maybe be happy that there is a delay.
I am located in Brussels.
In fact the device is not yet ready for the big mass launch. Posts in this forum show
they only shipped about 700 units.
I have been using my tablet now for three weeks and the browser is terribly slow and stalls or crashes frequently. The first few days it was smoothly but now it becomes slower and slower. Luckily there is an OS update since last Thursday which receives very good comments, but I haven't installed it yet. (have to do this with a PC - I use Mac)

But frankly I don't understand the cancelled order stuff. Is that out of frustration? Or did they already take your money? Or is it just that you lost confidence in the device?

Nokia faces a dilemma. Speed versus Quality. Both are needed to succeed today.
The launch was already planned in August. So, they finally launched it in the EU. I believe Nokia engineers are the most frequent visitors in this forum. So if they would have launched it in big numbers this forum would get bombed with complaints.
I have been studying and been working in Finland. Finns take everything very serious, sometimes to much. I am convinced they are working day and night to get this right ! Finns are also not very talkative and avoid to much public exposure. A complaint is a gift. But knowing the Finns, they will launch when it is ready and before you will not hear to much from them. Work hard, don't talk.
I believe a lot of Nokia engineers will do extra hours during X-mas holidays which again is holy to them. Maybe Santa Claus can help - he lives there ;-)
