About the 2-3 weeks:
We had the support telling us
a) it is software, wait for an update
b) it is hardware, return your device
c) never heard of this
d) Apple knows about it
now one(!) support guy speaks of 2-3 weeks for a software update to come along and you take this as an official statement?
How does this guy know?
Does he know it from the same source as the senior technical a few pages before who knew all about the problem and knew for sure it was bad hardware assembly?
What is fact?
Fact is, people who work with the new 13" rMBP are now in the situation that they might experience loosing hours of work under rare circumstances.
Imagine just as an example some non-tech normal mid-life customer buying the new 13" rMBP for writing a novel. After installing Pages and writing for 5 or 8 hours, suddenly the device is not responding anymore.
This person will not even understand the device has not crashed, but simply lost connection to the input devices. This person might turn off his or her device because he or she does not know better. And important work or information might be lost. In this example, creative work that might be unrecoverable at all might be lost.
So this is a serious problem. On this board the people know what to do to prevent the freezes. They know what to do if the freeze occurs so no work is lost. But there are many people out there who do not have a clue about all that. They bought a device that is supposed to just work.
You think Apple does not understand all this?
I do not believe Apple does not understand how serious this topic is. I do not believe they sit back and relax. I believe they work very hard on this and will release an update/hotfix asap.
Of course, it would be bare horror for Apple if the update would turn out to fix this problem, but create two new ones. So of course, it has to get tested as good as possible. Testing needs time. Sometimes it takes even more time than the actual coding.
Personally I think, Monday 4th would be fast. Wednesday would be still quite good. Friday is what I hope and personally expect from a company with Apple's values. Everything later than next Friday would not really match the claim to build the best computers in the world and give the best possible user experience.
