I think techies overestimate their influence. The Mac’s revenue was the highest it’s ever been last quarter. The lack of an escape key didn’t hurt sells.
Techies are a pretty big subset of MacBook Pro buyers, specifically, and that's the only line that has models in it with no escape key. The last quarter was the first one that the new MacBook Air was on sale -- the Air being one of Apple's most popular laptops and the one that had gone years without an update. That drove a lot of the sales that quarter. Were a lot of techies buying the Air? I don't know. But you know what the new Air has? An escape key. :)
