he seems to be like those rich people that don't show their wealth. i mean, he always wears the same clothes at those key notes. and the guy never shaves-it seems he likes the dirty beard look. so, as far as the iphone goes, he probably has both, black and white, and ones for work, the other for personal, with no cases. i had a similar "boss" that was a billionaire, but dresses like a bum. he always wore this ugly green coat with a big rip in the back, with these ugly grey slacks, and his brown loafers had holes in them, exposing his toes. At the company cafeteria, which is a big buffet, whatever he took, he would eat everything, not leaving a crumb.
