You must not go through the plug/unplug ritual much. It's a pain, cords tend to get lost, you don't have enough cords for every location, and the connectors wear out. Sure they are working on standards for wireless power that don't require a specific location but why not take advantage of what works for now?
I for one am eagerly awaiting support from all the handheld devices I use frequently. I'd love to have a desk where the entire surface can charge devices and a laptop that can charge that way. I've considered getting one of the cases for my iPod Touch that charges it this way but I'd rather see a standard before I spend my money.
