"Are they small issue? Sure, but they fix real problems. The need to switch graphic modes by logging in and out is not a big deal but it’s inelegant. It costs wasted cycles. It makes things harder for the user. Some engineer was bothered enough by this to fix it. It’s now a feature. It’s now the standard on how this function should work."

Details, Details, Details. Why Apple’s MacBook Pro refresh matters more than you think «  GartenBlog

I don’t get why Gruber pointed to this.  This example should actually be something Apple should be partially ashamed of.  For all we hear about Apple not shipping things until they can do it right (cut and paste, multitasking), they shipped something that was horrible and worse than the other solutions on the market.  Other solutions that shipped before Apple’s log out and log back in were hardware switches that just made the screen momentarily flash or detecting when it was plugged into an outlet.  I like both of these better than Apple’s old solution.  I do agree that the new solution is great though and the best in breed.  But this still partially is complimenting Apple on the fact that they essentially shipped a feature that was equivalent to telling a Linux user “restart X when you plug into a projector” in the days before RandR.  It’s not a small issue, these things are what we expect Apple to make a big deal about and never ship crappy stuff in the first place.
