Cellphone9 asks "What's the worst phone you've ever used?" The Nokia 6708 was definitely the worst phone I've ever used. While this smartphone was one of Nokia's few attempts to utilize the versatile UIQ interface, the battery drained too quickly, the camera wasn't worth mentioning, and the speakers were too soft to be useful.

But perhaps the greatest sins of the 6708 were that its keypad only let you input numbers and that there were no navigation keys. Operating the Nokia 6708 was reliant on the stylus and the touch-screen. This meant that, unfortunately, even simple procedures such as selecting menu options and typing text mandatory two hands!

Worse, it sometimes took forever for the 6708 to respond to keypresses. That alone killed the phone for me, as I value responsiveness above anything else.
