Most phones have the same features, the way you go about accessing them is different. Like you I've always had Nokia phones cos I love them. My wife has always had anything other than Nokia, usually Motorola or Samsung. She currently has the D500, I have the 6230i. Mine is the better phone cos Nokias are so much more user friendly, its easier to explore and do the things you want to do. The best thing is that Nokia have finally started putting high-res screens and cameras on their phones, hence the 6230i is better than the 6230.
But, like anything else, if you change its only a matter of time until you get used to the different ways a different phone operates. I'm used to Samsungs and Motorolas now cos my wife hasn't got the patience to work things out for herself.
