I have a few friends (who shall remain nameless) who are often unreachable because they don't charge their phones when they should. These same friends should look into the new Samsung Blue Earth, which is to be unveiled in a couple days at the Mobile World Congress in Barcelona.
The phone is green, despite its blue color, and it's not just the integrated solar panels that make it so. The Blue Earth is made of recycled plastic, features a pedometer, and even software that reaffirms just how much you're helping the planet by using it. If Al Gore had one of these mobile devices in hand, it would likely explode.
Besides being handy and eco-friendly, the phone appears to be gorgeous. The solar panels reside on the back, and the front is a full touch screen. Despite the new technologies, it should fit nicely in your pocket. We should know more about pricing and availability next week.
Another group that might find this phone attractive would be those crazy outdoorsy types: campers, hunters, fish enthusiasts, and other sportsmen could extend their trips into the wilderness while remaining in contact with the outside world in case of emergencies. We'd like to see other phones with practical solar panels just for this.
