John Gruber – aka @gruber – on a theme I discussed yesterday, the difference between Apple’s view of the Mac platform versus iOS/iPad: “Developer uncertainty regarding the viability of selling Mac software is the last thing needed for a platform that is already facing a dearth of new original native software. Apple doesn’t have to make a platform-destructive money-grab policy change to ruin the Mac. They can ruin it simply by planting the seed of doubt that they might.”
