All excellent sentiments I enjoyed reading because I for one share them. It's not about time (it probably took longer to axe features than retain them), money (you don't make or lose on something that's been there for years) or progress (as if retaining AFP and HFS compatibility for older Macs would have somehow held back OS X from moving forward). No, it's about engineering foolishness. Nevertheless, Steve Jobs has the power to be as big a fool as he sees fit.
"Stay Foolish."
