How can a research tell what are Nokia's future plan regarding Ovi store? Regarding the OS? regarding third party's developed applications for the N900?

How can a research tell you that there won't be a voice navigation software, at least not 3 months after you bought it?
How can a research tell you that Nokia will not announce a free Ovi Maps with navigation for the N900?

The "do your research" argument, or in it's current incarnation the "ah, so you didn't do your research correctly" is somewhat suspicious to me.

How come every non sympathetic review/response about the N900 gets this irrelevant response?

Looks like the equation is simple:

If you find no lacks in the N900 - well, congratulation!! you did your research properly! Enjoy

If there is something you lack of with the phone - obviously you didn't do your research correctly , and you are a troll .
Sell the phone (for half the price you bought it for) and buy an iPhone because that is what people like you deserve!
