I know this is a bit offtopic, but come on, please stop this "do your research" propaganda against any complaints heard about missing basic functionality in the n900.

A research should be made, I agree, but also should not be overestimated. It cannot, by all means, cover EVERY aspect and feature the device might of might not have.
If the device have front camera but no video calls - that's a yet-to-be implemented functionality rather than "no video calls".
If the device has (a)GPS but no good turn-by-turn navigation software, this again should be implemented sooner or later, rather than be treated by the "hey, do your research before you buy" approach.

I should not digg the 'maemo talk' forums just to figure if the n900 has unique ringtons for every caller - I expect Nokia to provide it as it did for me for the last 10 years I buy its product: out of the box (same goes for MMS). No research should be SO comprehensive, as the research's Value Of Information must be taken in account when the research is done.
