That page has a date of 2006, and I bet the survey is older. A lot has changed in 6 years. Many people still write checks in the US, now. Back in 2006 most banks charged for online payments, now most encourage it.
You do have a point the pos system, and the marketing in the apple stores is pretty idiot proof. Maybe the managers at the apple stores are useless drones.
I find it strange the perception of when an apple employee is a "craptard" it isn't apple, but the employee. However when a M$ employee is a "craptard" it is how M$ works. As for M$ poaching, at first I thought it would be a bad idea, to bring white knights into the dark side of the forest, but after thinking about it, I would assume that Apple has hired Business oriented managers, of whom probably most spent their school years using windows, and the Apple fan boys won't think about betraying Lord Jobs, so M$ ends up plucking out the "best" Apple business employees, and leaves the Apple fan boys in charge, most zealots will eventually trip up.
