OK, I too want a new phone, and I want one that major companies are supporting by bringing out compatable apps for rather than endlessly seeing iphone/android/rim based apps..
But

The other week, I was out and about testing our wireless system, and i used my phone to take a packet capture, then I zipped it up, attched it to an email and then sent it to my desktop.

Tell me a phone you can do that with - I fell in love with my n900 all over again - yes this phone doesn't have major support, yes, Nokia have broken alot of promises, but it doesn't stop it being one of the most powerful, configurable phones on the market today, and that is for a phone that is 1yr old.

I do want a new phone, but because the n900 is so good, I can wait and see, rather than being in a position where I have to get something now as the phone is driving me up the wall..

Don't forget that there is still a great enthusiast community behind this phone that are still producing some amazing apps, so there is life in the n900 yet...
