I've had this phone for just under a week now, and I'm quite impressed with it. It's a S60 3rd Ed FP1 phone, so it's fairly packed with features, but I'm quite impressed by it's overall quality. Much better call quality than my Nokia 6300 and it feels like it's built to last - although only time will tell. There are some useful shortcut buttons - although the main center button and directional control could have been used to do more. Some minor features have disappeared - one example is control over snooze time, which can no longer be changed. It's a pity it's gone, but it's nothing to cry over.
All things considered, this stacks up very well against phones of it's class, although you realize it's a shame the camera is on the back when you go to make a video call (go figure Nokia ;-)
I won't be taking it back unless it breaks down, which doesn't seem too likely.
