well i like it...
ive had mine for a week now and love it..
i dont particullary play games so im happy with the new button presses instead of the joystick (i had 3 different k800i's and the joystick was always sticking so was a pain in the arse).
i couldnt care less about the fingerprints.. any phone with a shiny case is going to suffer that and i think people moaning about are just trying to find things to moan about!!
buttons are a bit weird to start with but at least they wont suffer with the same problem as the k800i... ie the labels coming off the keys (very annoying and is a known problem with that model)
i love the camera and it makes it feel more like a proper camera now than a phone with a camera and its much quicker to move between the modes now they have used the keys 3 to # to allow you change them.
the soft keys are fantastic and i love them cant see why people are having problems with them and the person saying they keep getting empty texts... have the phone on autolock and you wont have an issue.
the only issue i would have mentioned was that the software doesnt auto sync but the cd supplied is already out of date and the updated version from the site allows that now so my contacts and diary from work are now synced every half hour.
and lastly the flash can now be used as a torch (dont remember that option on the k800i) which is usefull as it the SOS option it has .. if i ever get stuck somewhere i need it that is
