news post for the comic
For those who don't follow PA, Charles (the guy pounding on the door) is a longtime apple fanatic, who they used to ridicule around a decade ago for his use of apple products when neither Gabe nor Tycho would touch them. They then chronicled how both of them had apple and their products. So this is certainly an interesting development.
FWIW Tycho has written about his use of Zunes in the past (though I don't know if he still uses them).
