Logitech VX Revolution (portable version of the MX Revolution)
cooling stand (with fans)
external hard drive for backups (Time Machine when Leopard arrives)
and AppleCare
I'll definitely second the VX Revolution. Picked one up, and have been testing it out with my PC (haven't gotten my MBP yet), and it is awesome. Great grip and feel and ergonomics, and it is smoother and more accurate than my desktop mouse, which is a Razer Copperhead.
