UPDATE: Here is a list of all the patents infringed: http://www.engadget.com/2010/03/02/apple-vs-htc-a-patent-breakdown/
I am with Apple on this one. HTC isn’t really to blame here, it’s Google’s fault, but that serves HTC for trusting an external company. Yay Apple!, they make the hardware and the software/firmware and it all works great. Slide to unlock? It is such a copy! As Steve Jobs said, competition is good, but Apple puts a lot of work into their research, so other company’s shouldn’t just steal their ideas.
