3g video calling and portrait mode is a phone capability. Then you said n900 is a mobile computer with phone capabilities. What makes you conclude that 3g video calling and portrait should not be implemented? Well portrait mode could be considered. Also if its a mobile computer why on earth is it under the phones list of nokia and not on the tablets? I mean common users surf the phones list of nokia for updates of new smartphones. Then why would they dump the n900 there if it wasnt suppose to be on the smartphone category after all?
