Haven't been to a tech talk in awhile, but I did when they first started doing them. I found them to be very helpful as an "update" to our WWDC experience. This was a few years back before WWDC always sold out.
Its not just some animation or visuals. Its a method. Nobody else came up with a method like this. Its a combination of actions, visuals, animation, and how it all works together that makes this a patent.
This is a perfect example of a good patent.
Because those ludicrous prices keep AAA games from being profitable enough to bother porting. If a publisher knows he can sell a real, high quality game for $20-30, more will come.
Yes there are MANY high quality games for free to less than $5, but there are many more that won't come without a higher price.
