I too have posted several detailed feature request/changes for OS X, yet have not recieved this survey. I'm getting annoyed as well.
I'm not just getting annoyed of not getting the survey, but I'm annoyed of how Apple is handling OS X Public Beta in general. Their OS X website, for example, has basically no info for Public Beta users, and what little information is there, is rarely updated. Of course though, they have all those pages for showing how the Dock and Aqua are 'so cool', complete with Quicktime movies. But where are the software updates? We know that there is a chance we will see OS X Beta updates, but when? Where are the tips and late breaking news flashes about OS X Beta? Where are the message boards that we can have one central website to discuss OS X Beta, and not constantly hunt around on 3rd party website UBB's like this? Why can't I combine Versiontracker.com, osx.macnn.com, macosx.com, and appleinsider.com into one, Apple branded website?
I don't think I'm asking too much. It's time for Apple to do us a favor and make us feel like welcome OS X Beta Testers and stop leaving us in the dust like they do so many times.
