That's still a pretty stupid idea! There's more folks looking to get a hold of a physical media disc than a download. I was reading TUAW yesterday and people brought some interesting points. First, what if people dont have access to broadband? Sure, we are in 2011 that still doesn't mean everyone has high speed internet. A 4GB download might take a while and can be troublesome for some folks.
Apple continues to be so adamant on getting rid of physical media that it chooses to go this route. I don't like it, but hey what can we do? I hope they release the disc after release.
