(a) in order to say that someone's statement that they "expected" something to be done at a certain date is false, you have to prove that they did NOT EXPECT IT.

(b) do you really want them to put out the update now regardless of whether it is ready? I personally don't want a fix that is known to be defective. Maybe you angry people don't care what happens to your expensive tablets, you just want the fix out when you expected it?
