That Apple is able to get a patent on the exact outline of a microphone icon, is the biggest testament to how utterly ******** the patent system is.

Personally, I think some icon of a brain, or the act of searching, might be more appropriate than the Siri microphone. Frankly, I never understood why Apple chose to use a microphone logo to begin with - I don't associate Siri with sound recording, I associate it with voice processing (which I don't associate with a microphone) or with searching (for which the silhouette of an eye might make sense. Though now that I think about it, so might the silhoutte of an ear...).
