Boring old symbian here. :hmm: My brother has blackberry, but it doesn't impress me. I've operated nokia, blackberry and samsung(partially). And I personally go for symbian. I found it very easy to operate. It is suitable for anyone.... Oh, in that case, I take it back.., :X symbian rules!
I recently purchased a Nokia 701 with Symbian Belle.
I have had maybe 6 Nokia phones since my first one in around 2002... I think I was in the 5th grade. Nowadays kids get their first superfancy phones before they start going to school. I had a Nokia 3300 ;D
And when I lived in the US, I couldn't get a Nokia phone with any plan. It was sad.
