Again, I will repeat what I have said in other threads. Most of the "problems" that you speak of are very minor and will likely show up in rev B/C/D and so forth. For example, you cannot guarantee 100% (in fact not even 50%) that every single unit of rev B will have perfect non-dented, non-scratched, non-keyboard-warped machines, because such errors are an intrinsic part of the manufacturing process.
And plus, many complaints are about subjective things, like design preference over this and that, etc
