I am not sure what the samsung black carbon is so I can not say anything about it.

Just by seeing the specs and the pics from the Nokia N95, I would say this is a winner. Nice features and the build of the phone looks good. But i am not sure about the performance of the UI. If it is like the N80, then I say go for it. However the UI of the N80 became sluggish at times.

The SE K790a is a great phone. Great pictures, great feel, great battery life. It has lots of features. Even though it is a camera phone first, it does mp3s and movies real well. UI is smooth if not fun to just watch as you scroll through the menus.

Im sure that if i got to play withe N95 i would love to use that phone.

Hope this helps.
