Like cover flow and any other viewing options that I'll never use other than the basic list, is this a "feature" that can be turned off and ignored?
Yes, the keynote also showed it in the traditional list view. I just hope they didn't lose any of the other current functionality.
It's not easy to know which things will fly and which will bomb, so I'm not going to poke fun at Apple here.
When Ping first arrived, pretty much everyone declared it a bomb, and they were right.
Ping wasn't replacing an existing functionality.
But that has nothing to do with who was the head of Apple at the time and what they might have done. There are plenty of examples of botching existing functionality on the last guy's watch - iMovie, FCX, releasing a shuffle with no buttons, etc.
