People are expressing their anger on twitter as well, on blogs, in forum comments everywhere. There is nothing unusual about the discourse here it's a reflection of what people are saying about the product.

If, like me, you want Nokia to survive as a competitor to Android and the iPhone you should be asking why Nokia cannot do this one simple thing rather than why people should just shut up about it.

Imagine how many posts simply wouldn't exist if after the summit where they handed out 300 units Nokia issued a press release saying "We don't expect the N900 to be available at retail until November 25th" (or whenever). That's a full 5 or 6 weeks in which people would be talking about how they're looking forward to the product coming out instead of "What's happening? Where is it? What did newegg say today? Who wants to ring MPD?".
