First I'll say I own 2 N900s 'cause I plan to use it a long time.

But the reason it 'failed' is obvious: lack of functionality and polish. We all know the things it can not do that it really should. And the bugs further diminish its capability. Like how the streaming radio song information will not update in the media player. Or how the media player often will not show the new media loaded on the N900.

And another: the fact that if you rename a file in the file browser the device will not show you that new name.

It is filled with this kind of stuff that is infuriating after a year or more of owning.

Everyone has their own irritations like this. Most of us still like the device despite the flaws because we like what it stands for. But most people don't purchase a phone on principle.

And there you have it, IMHO.
