Milhouse, I'm sure you know that we're talking about Nokia, a company with a long history and a lot of experience in providing hardware/software in mobile space, not a new startup.
It seems that they really expected everyone to jump ships and buy a N800 as soon as they announce it. The issue is that they can't expect to maintain a community (which actively contributes back), if they leave previous generations behind without addressing their serious bugs.
We all know that they've practically ignored 770 Bugzilla and concentrated on the next product, N800. How many sane people would keep buying a new tablet, if Nokia repeats this every year?

The worse? Those who can't stop singing N800 praises hoping to get a N900 or whatever it is for free, perhaps.
It is a very good idea to highlight the benefits of a new product and encourage the manufacturer to continue with improvement and innovation, but a community (Maemo, Internet Tablet users...) grows through constructive criticism, identifying pitfalls and helping to fix them; that's what's lacking in these love-bird postings that bear no meaningful message for anybody (and I'm not referring to you).
