Q: How long does the update take to install?

I started the Apple TV software update at 8:00pm, hoping to watch a movie that night.  After two hours, the update was still not complete - the status bar was stuck in the middle - so I left the update running and went to bed.  The next morning, the update was finally complete, so it must have taken several hours.  I have since installed an AirPort Extreme router - perhaps the next Apple TV software update will go faster!  Updates on my iPhone, iPad, MacBook Pro are complete within minutes and I expected the same with Apple TV.  All in all, I really enjoy the Apple products and technology.
