What essential accessories should I buy for my new Macbook Pro?

On Saturday I am finally getting my Macbook pro! Other than a cooling stand and a Hard Drive and excluding memory what essential accessories should I buy the same day as I buy the laptop?

Thanks

I'd be sure to purchase a good laptop bag to carry your MBP in....

Depending on the model, you might want to get a multimedia card reader for the ExpressCard 34 slot. A Magsafe airline power adapter might be useful if you do much traveling. If you'll be using your MBP as a desktop replacement, you should get a Bluetooth Mighty Mouse and keyboard so you can position everything in an ergonomically correct way. An Apple Remote will come in handy if you use the MBP to watch movies on an external display. You might want a good neoprene slipcase and a laptop cleaning kit.
