A couple weeks ago, we posted about TwelveSix’s PlugBug, a cute little attachment that plugs into your standard MacBook MagSafe charger and gives it a 10W USB port, perfect for charging your MacBook and iPad simultaneously.
The PlugBug’s an ingenious little idea, and I’m reviewing one now. However, PlugBug’s days might be numbered: a new patent says that Apple is working on a universal power adapter that can charge MacBook Pros, iPhones and iPads, all at the same time.
