To me you guys sound like people that need a "little bit more" from their device, so I think its no wonder you're feeling at home with the N900.

I know if I ever switched over to the iPhone I'd probably enjoy the stability and UI of it, but once all that eye candy wore off I'd like to actually get something done on it. which I couldn't do.

The N900 hasn't just put me off the iPhone, but also any other Nokia provided handset as there's just no going back from this amazing experience. I just cannot go back to Symbian, eventhough it offers more functionality than most smartphone platforms. To me the N900 is a great blend of eyecandy and functionality. Winning combination for me!
