Comparing the N900 with the iPhone is like comparing a sailboat with a train. They are two completely different devices that are geared towards two completely different type of users. If you are even remotely interested in how it stacks up against the iPhone I suggest you consider buying one or one of the many iPhone competitors.

It is very important you are aware of what the N900 is and what it is not. Its not a full featured phone. Its a full featured mobile computer with phone functionalities. It has some serious software limitations at the moment and only the future knows how Maemo and the N900 will turn out!
