I have a unibody macbook (late 2008) and I am setting up my clamshell setup. I play a lot of games and I require mouse + headset (both usb). If I use the apple keyboard with two usb slots can it power a mouse and headset? I heard that it cannot power ipods and stuff like that but that does not matter to me. I tried googling for awhile but all the threads I found were from 2007. Edit: Also, i've noticed that my hands have started to show early signs of problems from possible typing and/or gaming. How is this keyboard when it comes to stress on the hands?
