Well i would imagine that plugging in my alum wired keyboard to my unibody 15" MBP i would be able to use my usb stick on the left open usb port. I have my wired mighty mouse on the right side and it works fine. Anyone else have this problem? I guess i will have to go buy a USB powered hub, because the usb ports are so close together on the actual laptop that i can't have my usb key and something else plugged in at the same time.. Anyone else have this issue with the "low power" warning?
