Available in a choice of black or white, the K550i is a compact and lightweight phone that looks very attractive (it's much less of a brick than the K800i for example). The buttons are smaller than most Sony Ericssons, but are not difficult to use as they are well spaced out and project a millimetre or so above the surface of the phone. The display is a good quality TFD LCD screen that retains good visibility in sunlight and is of a high resolution. At 176 x 220 pixels, it isn't as fine as the display on the K800i, but it's double the number of pixels of the K510i and is as good as anything in this price range.
