Reflect for a moment. Imagine you are going to drive a long way - say 600 miles - and the people at the other end want to know when you'll arrive so they can have a meal ready. How can you predict? You can give them a vague ballpark, and hope you hit it, but with the uncertainty of traffic, weather, that accident on the m5 and a couple of tractors, the chances are you'll be wide of the mark. You can make a worst case estimate, give them that and then hang around in the playing park opposite their house till the time you said you'd arrive. (Which is roughly what most manufacturers do - someone has already said that the big release video game recently was preceded by days of it piled up in stores Not For Sale). Or you can call them up and say "I'm now leaving" and hope they can be mature enough to make a guess about when you'll arrive and be flexible about the possible transport complications. Which is more or less what Nokia did. Peter's comment was your n900 calling you from Korea and saying "I'm now leaving". I guess it just got stuck behind a tractor somewhere on the High Seas.
