Paul Allen lives in a yellow submarineOkay, okay. We don't know if Microsoft cofounder and tech-investing dilettante Paul Allen has actually moved into it. But the Dubai Luxury blog reports that he's shelled out $12 million on a yellow submarine. A 40-foot-long yellow submarine. You're a Beatles fan, Paul; we get it. But Paulie, baby, want to know why your net worth is only a third that of fellow Microsoftie Bill Gates? Dumbass purchases like this.
