After the MacBook Air, what next?

MacBook Water: splashproof to survive your eXtreme lifestyle, or at least a spilled latté when you show it off at Starbucks.

MacBook Earth: the natural organic sustainable recycled biodegradable cruelty-free dolphin-safe fair-trade computer. 10% of all proceeds are divided equally between Greenpeace, PETA, and BDS.

MacBook Fire: oh, wait, they already make those.
