For all the bitter comments I posted here, I would like to add that I like the N900 very much. I like the look and feel of the UI, even if there may be room for improvement here and there (therefore I am a little sceptical about the switch to Qt, since the demos I have seen are not that encouraging from the aesthetic point of view, however as long as they stay with the UI design, I don't care what toolkit is used).
I accept that initially the software is missing features, but I expect Nokia to remedy this in future updates (for the N900, to be sure!), even if not all promises can be held.
Otherwise I would have to assume that Nokia is treating its customers like idiots.
