I think what is the most disappointing is the lack of communication.  All these promised are coming out for things to be released...like on Monday, and it's now Wednesday and there's no release - which is annoying but not as bad as the fact that we've all been left hanging thinking something was due on monday, but now it hasn't arrived...so when's the next promised date?  I understand projects can drag on and things happen that cause more bugs to come out - it's kind of just the nature of developing I guess, but you really really need to keep the customer informed about what's happening, especially when you shoot past so many promised dates.
