The K660i looks and feel stylish, it looks slimmer than previous K series (compared to the K750i and the K800i) and the silver edges adds to its cachet; its front face carries a 2-inch 320x240 pixel, 262k TFT screen which is bright but falls in the average category as far as colour rendition is concerned.
Directional Controls aka the joystick which was popular on older K series, has been replaced by a 4-way pad, which is sturdier but feels less intuitive; the K660i retains the six-button model found on most web-capable Sony Ericsson K-series mobile phones.
The keyboard adopted small rounded illuminating buttons, some of which (four of them on the right : 3, 6, 9 and # keys) have secondary functions which kick in when browsing and come handy for shortcuts and the likes.
The K660i has the ability to surf the web horizontally, this means that you have a larger landscape screen area which SE calls "Horizontal Web Browsing" and the buttons allow you to zoom in and out as well as move laterally along the sides; no iPhone kicker but still quite good.
The problem though is that while the screen does rotate, the keypad does not, which means that you might have some issues using the keypad to type.
The K660i is compatible with the Opera Mini Browser (not the new Mobile version) should you want to swap the default browser.
