No guys, wooly's right.
Burlington Coat Factory has been using Linux desktops for a decade now and they haven't had any customers. This piddly little start-up called Amazon.com is using Linux "in nearly every corner of its business" The result? No customers. Dreamworks Animation uses 1,000 Linux desktops (as of 2007) and used Linux for animation and visual effects in Shrek 3. I don't think anyone saw it, much less even knows who Dreamworks is... Google uses Linux on desktops in its corporate environments. I don't think they've made a nickel's profit...
