I don't really disagree that more stuff would be nice, but here's the opposite point of view. One of the best things about the N900 is that it's Nokia.

I love running things I can hack around with, my phones don't escape this and have often not run properly in the past. In my search for a more open phone I bought an Openmoko Freerunner a few years back.

It was open and ran linux but other than that... the build quality was poor, the battery life was terrible, the handset was only 2G, the sound subsystem was dreadful, IMHO there was no GPS app as good as Ovi maps (!!), it echoed all the time, dropped calls, didn't have a stable software stack and generally was a pain to live with.

Now I have a linux phone, and because it's Nokia I know it works. I can play around with it a lot but at the end of the day it still makes and receives phone calls.
It's always been the rule with me and my crowd - want a phone that works, you buy Nokia. And now they have a linux phone it just all makes sense.

As I say - not a disagreement with the poster above really, just a different perspective.
