So let me get this straight...Apple releases a product that doesn't work right as advertised/promised and expects its customers to upgrade the OS months down the road in order to (supposedly) perform the way it was supposed to perform in the first place. Mmmmmm, sorry...that's either misleading advertising or if it's a bug, Apple should claim it a bug and address it.
With the passing of SJ, it's clear that Apple no longer has the long-term vision to REALLY innovate. Every product launch in Cook's era is just an incremental update of existing things, rMBP included (i.e., a crippled retina display and nothing else new).
Time to sell your Apple shares, because the company will be moribund in less than two years...you reat it here first.
