I know what MPD say on their website. But there are companies out there who say on their website that they have n900 in stock. I have no reason to trust them. I am not a very trusting person when it comes to online suppliers: I don't even have a lot of confidence in the nokia shop itself.

Now, if lots of people come in and tell me that X supplier is reliable, trustworthy etc, then I might be persuaded. Otherwise, I might go see what Carphone Whorehouse have in stock and can sell me over the counter. Or stick with the supplier I know.
