IMHO if I have to do anything on the n900 for longer than 5 minutes I will use my Mac and connect to it via SSH. I suppose its what purpose you use the device for that depicts how long you use it. For me, its firstly a phone followed by a useful device for email/browsing when I am on the road and without my Mac albeit I almost always take my Mac with me too. If I am in a restaurant or somewhere where I dont have my Mac then it is wholly a phone and nothing else. I mean, it isnt cool to take out your phone and start browsing or answering emails at such places.
