Yeah, I'm personally not too fond of all the step analogies... As if there would be no further steps after step 5, as if step 4 i.e. N900 wouldn't already be a very good device. Every next device is basically a step forward.

Well, as long as it is not mentioned in the marketing material of the N900, perhaps it doesn't matter all that much. Anssi Vanjoki is entitled to say whatever he pleases.
