In the same way, you have also missed our point - everyone already knew the disadvantages of n9. Yet we bought it anyway,some like it,some less.
It called doing research before buying. As far as I'm concerned, n9 does the basics just fine.

Lumia 800 has 1 major disadvantage, over dependance on zune/cloud storage(i.e. $$$ for data rates),that alone deters me from even considering it. As for n900, no other phone thus far is even on par with it BUT I would not gotten it due to it being a slider phone, too bulky.
