The first generation iPhone (2g), the third generation iPhone (3GS), and the fourth generation iPhone (4). The straight edges of the face of the iPhone 4 give the illusion of a larger black bezel around the screen, notably above and below the screen.

The curvature in the first three generations gave the illusion that the bezel disappeared earlier. The second and third generations (3G and 3GS) had much more gradual curves in the back, making the phone look thinner when viewed from the front and sides.

Associated Press writer Jonathan Fahey reports the results of an Electric Power Research Institute study to determine how much energy an iPad consumes in a year. “The answer: not much,” writes Fahey, noting that “the annual cost to charge an iPad is just $ 1.36.” He adds: “…if people are using iPads instead of televisions to play video games, or ditching their desktop computers for iPads, the shift to tablets could mean lower overall power consumption.”
