I did a thorough research in the smart phone segment on Samsung, HTC, Sony Ericsson etc. My priorities on a smart phone was :-
Camera(better pixel rate and flash)
Rigidity in design
Shock proof
downloadable Route map
From my knowledge I can say that there is no phone is available with 12 Mega Pixel and Carl Zeiss lens
And its design makes it so rigid that the phone will be able to work smooth even it drops several times from our hand. you can see a drop test for Nokia N8 in you-tube.
One disadvantage about this phone is, its not that much fast as we compare to other smart phones like HTC or I-Phone.
But this slow performance issue is overcame with the launch of new version of Symbian called Anna came with version number of 022.014.
