phones like N8,C7,C6-01 are having three home-screen ...& also v can add widgets to home-screen...as in android..
wht r other differences apart frm android app store & ovi store...
which OS is more preferable if i get both in same price?
Android is the better OS in this case. Symbian is essentially dead since Nokia (the only ones using it now) are switching to Windows Phone 7 before the end of the year.
Android OS is one of the most used OS in the world. You can find free, new and cool stuff with Android. I am using Android and i find it is one of the best OS.
