@Suyash
One expects more when paying >21k for a phone....
not just to set different walls on homescreens ...even the year old Samsung Star can do that ....
Except the camera there is nothing to look into N8......and if it is the reason one buys the device....get a digicam and a android smartphone
N8-21.5k
LG O1/Galaxy3 ....both have proccy speed equivalent to N8..
Well the thing u missed was ......that it is more of a closed platform....
No Modding...
No rooting....no cynogen ...what would onw do without it.....
No usable APPS.....damn symbian..not even a simple one to get movie locations and booking

.......
@OP
if you want to invest into a N8 don't buy for the above reasons posted for N8...it is a decent phone..u might like it as you seem to be new to smartphones but you will soon grow out of it and will demand more but then ur device i.e if u get N8 will not be able to cope up and then maybe u will regret ur choice....
So if you are looking for a phone which will last u for sometime and will grow with u get a HTC desire/Galaxy S/SL...or even a Morotorla defy(no HD).....
