Well, looks like there is a new patent that Apple filed for a wireless charging system. In the patent it appears that there is an iMac-looking device and the wireless charge would then charge the laptop and mouse, basically eliminating the need to have batteries or have to replace batteries.
The patent also looks like there is an iPhone or iPod Touch on the desk that would benefit from wireless charging.
This looks very promising. I can imagine charging my laptop, iPad or iPhone from a distance. How would this affect your life if you no longer had to plug in your devices to charge them?
