I like both but am wondering if anyone with knowledge of both could give any recommendations for one or the other? Form factor, UI, camera & video quality, and reliability are all important factors (in addition to actual voice quality).
although i prefer the slider form factor, the k800 has a beautiful finish, whereas the d900 feels very cheap and plasticy.
in terms of the camera and UI, SE wins hands down, but the d900 does better with video.
