I recently got a macally icestation for my MacBook Pro. It works quite nicely. Their site markets it to work with Powerbooks and other laptops. The only problem I see is that the CD slot is on the front of the MacBook Pro and therefore putting in CDs when it is on the icestation is a bit of a hassle. I don’t use a lot of CDs though. Overall, it’s much better than having the MacBook Pro just sitting on the desk.
