I'm with Quim here, the "noise" really isn't exactly unexpected, and if you avoid the (obviously) noisy threads, you find that most of the forum remains civilised.

Honestly, if I was waiting for an N900 like the most of the "noisy" posters, I'd probably be a lot noisier too, or I'd just be avoiding the forums completely.

Just a little point on the "delayed again" comment. There has been only one official delay -- the N900 was coming out in October, and now it is coming out in November. All the rest is pure speculation by bored and frustrated posters hassling people who really have no idea about any of this stuff and taking the random things they say like gospel.
