Was this product ever a good seller?
I personally forgot all about it.

Honestly? no not really. When the original product tanked they pretty much had a huge slope to climb up, they released the QD model hoping to bring up some relief to the system but in the end it pretty much faded away out of most retail spaces without ever making much of an impact. Most casual gamers didn't notice it and the ultra-core kids ended up branding it for life with hatred.

So yeah it sold pretty sub-par given the original focus. In terms of gaming, it was decent enough but I think many still wanted a seperation of game and phone in the end.

I think one of the biggest problems is that with the advances in cell phone technology the N-Gage really didn't offer much that many other phones could not offer already.
