While the display inside the laptop will be used normally, the outside display is expected to house photovoltaic cells used for solar charging, and at the same time act as a secondary display that houses sensors that can be used for touch input as well. In a way this sounds like hybrid Windows 8 devices we’ve seen hit the market, with the main difference being that Apple’s system will feature solar powered charging capabilities. It sounds like a nifty idea although we’re not sure if Apple will even implement such a system. After all most Windows 8 hybrid devices tend to be rather thick and with Apple placing such a huge emphasis on making devices light and thin, we’re not sure if that is something they’d sacrifice just for the added features, but what do you guys think?
