Also, who is to say that $4bn/year isn't "fair" when video is an essential part of Microsofts products?
Don't get me wrong, I hate patents as much as everyone else here, but I still think this lawsuit poses as a very nice example of why free video/audio codecs are important.
We had the same shit with LZW/GIF patents a decade earlier and all the warnings were ignored and laughed at ("Nerds with tinfoil hats" ~Gruber). Microsoft (and Apple) doesn't deserve better for their arrogant stance on this issue.
