My phone does what I need it to do: it receives calls, it allows me to make calls, I can send and recieve messages and it has a calendar function with alarm clock......that's it, that's all I need.
I've had my Nokia (housebrick) for about three years and am perfectly happy with it. Don't see the need to upgrade unless it dies.
