your ideas, because, let's face it, you've done your own share of stealing ideas over the years. "Slide to unlock" should not be a patentable idea. Active links in an email should not be a patentable idea. Get over it and just build something better. Yes, I guess that's pretty useful. I do AirPlay quite a bit with my iPad but I've never really felt the need on my Mac. However, I did just stumble upon this thing calles AirParrot which looks pretty interesting. I wonder if AirPlay is an open standard? I'd guess not, but it appears that non-Apple tools can emulate it...
