Taken from the AAN review earlier in this thread:

But roughly translated there's about 3 million N-gages out there, and sales of 80,000 to 90,000 a month are probably realistic. A million and a half units a year is a failure?
AH HAHAHA HOOO BOY

Well, they made some good points. 80,000 units a month, though?

Wait, where's the part of the article where they explain the differences with the thing?

It seems to have a smaller frame (that or the screen is bigger), as the screen is larger in comparison to the frame than on the other QD they're showing (which I assume is a reference pic). That article confuses the hell out of me.
