"It's always there in my pocket, there's no thrashing about, scrambling for the right color. One can set to work immediately, there's this wonderful impromptu quality, this freshness, to the activity; and when it's over, best of all, there's no mess, no clean-up. You just turn off the machine. Or, even better, you hit Send, and your little cohort of friends around the world gets to experience a similar immediacy. There's something, finally, very intimate about the whole process."

-David Hockney on his appreciation for his iPhone and the Brushes application, in Lawrence Weschler's piece on the artist in The New York Review of Books
