Here is a new weird-looking concept phone from BenQ-Siemens, the SL98 Slider. The handset looks more like a pocket calculator, with the small external display to show caller information and other stuff. Its main screen slides out on the top, just like the keypad on a standard slider. It feels pretty unusual, to be honest. Once the display is out, one can take advantage of a digicam located on the back of the screen.
It is still unknown, whether this phone will come into the market or not. But we will keep you informed.
