I had the original N-Gage. It was my first smartphone. It had some stupid design decisions (difficult to remove/change the game cards, sidetalking...) and technical limitations (I think that only one program could use the internet connection at a time so opening the web browser stopped the emails from syncing) but in general it was quite a good smartphone for it's time.

And Pathway to Glory is still the best mobile game that I have played.
