There have been other watch-phones, but those have been mostly by Chinese companies that nobody has heard of. The exception was LG's Korean rival Hyundai and it's W-100 Watch Phone as I previously posted here.
Implications - The LG Watch Phone features a Shine-like bar with scroll-action to help users navigate the device's various functions. Adding to the overall effect are the voice/audible prompts which announce the successful completion of each assigned task. Best of all, the phone is fully integrated with Bluetooth technology. This is definitely one of the better products of its kind to come along in a while. You can check out the hands-on video of the LG watch phone below!
