[John Carmack] is kind of a hermit, so for a long time he would refuse to carry a cell phone. After we had our child, I was like, ‘you really have to have a cell phone!’

So I got him a cellphone, and John, being John, started fiddling around with it, and checking into the technical specs. Down to the bone, all the way down to his little hair, he’s a true geek, and if he could have, he probably would have taken it apart and reassembled it! -- Katherine Anna Kang, Gamasutra.com
