Failed??

It is a machine for the intelligent geek.
In that it has succeeded beyond any other device out there.

If I met someone carrying and using an n900 I would know instantly
that they are definitely not a dimwit or a *****,
regardless of whatever else they may behave as.

I absolutely cannot say that about people who rely upon iPhones, Android etc.
Not they they are all hopelessly clueless,
(many use those devices because they have no time/talent for tinkering
and-or maybe depend upon it for basic functionalities, trendiness, etc.)
but that you cannot judge that book by its cover as well as you can the n900.

With the n900 there is a prerequisite of some spark of intelligence
just to be able to use it for more than a paperweight or fashion accessory.
(Yes, there seems to be slew of apps just to make it exactly such a thing despite all that)
