Also, Lion did actually come on an installable USB drive (which is more expensive than the App store Installer app). Not Mountain Lion though. Creating bootable disks (USB or DVD) from the installer app is trivial. Also his other point about losing all installers is actually a point in favor of the app store distribution model. They're always there unlike a physical disk which can go bad on you. Time machine and Migration Assistant errors he rightly cribs about though. It is imperative that they work right. All in all it's strange that one of the people who did seminal work in the early days of UNIX and C comes off looking like lost layperson. You'd expect him to be able to be able to deal with this way better.
