I know this might be a dumb question to ask, and yes- also about using it with a Microsoft- related product (hey, xbox 360s are one of few good things Microsoft makes!). Anyways, I don't own a MBP, just waiting for the new ones to come out, and had a curious question in mind. Even though the usb hub for Rock Band (4 usb ports) has to use a power adapter (I don't know why)... would it still work with 3 extra usb ports on the MBP? It might seem dumb, but if it doesn't work, I'm probably better off buying a better one without the need of a power adapter and with possibly more usb ports. What are some good ones out there? Thanks for any help. I'm typing very uncomfortably right now with a fractured collarbone after a ski collision (on someone else's part, not mine).
