I airplay all the time, but mostly for other people (presentations, kids, etc). There is a noticable delay, about .75 seconds. Makes it impossible to use computer and AppleTV display at the same time, the delay messes with your brain.
Not sure how they plan on doing this with Mavericks. If you have HDMI, you don't need Airplay as you can plug right in to a TV.
