I was an early employee of Aereo (the case mentioned in the article where Breyer went on about phonograph record stores), and I worked there when we were sued and ultimately won the appeal in the 2nd circuit, when we won in 1st circuit, when SCOTUS granted cert, and ultimately when we lost.
One of the strangest parts is that you have no idea when they'll issue your decision. They give a certain amount of advance notice that they'll be issuing decisions on certain days, but you don't actually know which decisions.
For a couple months after oral arguments, we had probably half a dozen mornings on pins and needles while we'd wait to find out if they're going to decide our case. It was really, really hard to concentrate on getting anything done.
Another fun fact: Clarence Thomas has only asked 1 question during oral arguments in something like 10 years.
