Apple is so kewel...
Not that, but just trying to think of when Apple sold the last white Mac. They do sell white iPhones, along with Space Gray, and Gold, along with the 5Cs in multiple colors, including black.
I just checked: it was the White Polycarbonate MacBook, sold from May 10, 2010 (five years ago) only through education channels. Discontinued three years ago last week on February 8 2012.
