Worth buying? depends on your reasons for choosing N9.

I've never used it (for a long time) but I played with a friend's N9 which came for USB fix.

Hardware is awesome .. I'd buy one just for that.

Software/apps -- the Harmattan community is still supporting it quite well, so many things do work. An unofficial "store" does exist ..

some people feel the N9 was a regressing when compared to the N900 .. in some ways, I agree.

At the end of it all, just choose what you believe will satisfy you in the long term ... Do your research on the strengths and weaknesses of both devices.

Maybe we'll just see you on the N900 side
