Crappy experience i know, but to put it in perspective, you've been the victim of a hardware fault and further to that the cons of piracy protection. Which, has to be put into effect due to the inability of many people who decide to steal the work of others.
2 month wait to get working hardware that sucks most, i would be livid.
As for the AU architecture moving forwards, i think that's a good thing, AU development has been stale for many years, comparing to VST (as a technology) it's way behind... Apple are moving towards a universal system whereby plugins will work on iOS and OSX, this will really help developers big time to put a single product out to multiple marketplaces.
In my experience as an app developer, Apple are pretty good in getting the libraries and dev environments out to *anyone* with a developer account, and there's a wide range of resources available to you, even the smallest of developers do have a relatively decent window of time to prepare. I'm presuming that applies for those working on audio units too, but maybe it's a dark cold niche place.
I remember when users were up in arms at apple because of their decision to commit to 64 bit apps, developers had years to develop third party AU's to be compliant, yet many didn't. I think that strong decisions from up top (i.e. Apple), ultimately, is very good. Compare to Microsoft, they still can't get it together in regards to 32/64 bit compliancy on their flagship products (Office etc.) - at least there's some direction being outlined here.
I don't know how most Logic users feel, i'm not wholly dependant on Logic for an income, nor do i spend on over-powered gear that would serve me no additional benefits - i work very much within my means and am appreciative of the technology available to the modern musician. So, that said, i only view these developments as being LONG overdue and so pleased to see things moving at such speeds.
The option exists for those that don't want to ride the train of course.
