This is one of the things that makes me not like Apple, in real powerful way. Not for upgrading the screens, that's a good thing. The bad part is they're doing it too late, silently and in hindsight.
I made some friends make a first time switch to Mac, a couple of them to uMB's. All of them remarked on the crappy screen, figuring 'more money - better parts'. Now, after reading about Apple 'admitting' they replaced the screens in newer models...
Wonder what "#1 customer experience"-company would say to them, should they call? 'Sorry for screwing you over, but we're Apple - we do no wrong'?
Now, raise of hands, who here thinks they'll buy Apple again? 🙄
Me, I just remember the golden days when Apple really were all about 'premium quality', and not flashy crap...
