Those of us who can plug directly into the grid likely don’t think much about where our power comes from, but for people living in remote regions of the world or militaries operating far from the nearest three-prong outlet, being able to pack power with you is a priority.

Elastic Eyesight: For the 314 million people around the world with blurry vision, just put on a pair of Joshua Silver's AdSpecs and inject light-bending silicon oil into the plastic lenses until the world comes back into focus.

Well, the first review of the XO laptop from the One Laptop Per Child initiative has been published. Remarkably, this BBC-sponsored review was performed by a real live child. Although written by his father, Rory Cellan-Jones, the meat of this matter is supplied by his son, Rufus Cellan-Jones. Whats your take on supplying XO laptops to developing nations for developing the minds of their youth? Do you have firsthand experience with an XO laptop? If so, please post your observations in our comments section. —Dave Prochnow
