The underlying Operating is more of a Desktop than it is a mobile phone. Desktop software runs on the N900.. not just "phone"-ized software written by random people. It is easier to port desktop software to the N900 than any other device on the market. This makes it more of a mobile desktop than a phone. Now, the fact that said desktop software is *not* available yet goes to the youngness of it. In Maemo 4 we had Gnumeric, Abiword, etc all ported. Which means I am using *exactly* the same software on my desk at home, as on my new "phone". This puts the N900 into a category of it's own.
