I tend to think Nathan is on the right track. As an example, I use launchbar a lot on my Mac. It's a good experience, lets me use the keyboard more, but it doesn't radically change my life. My beta ran out, life went on. I'm a little suspicious of speed claims, I can never tell whether steve means "fast on a powermac" or "fast on any mac". I'm sure that metadata would save me a couple minutes every day on my computer. I'd probably find good uses for it. But would I pay $130 for it and a few other updates which I seem to be fairly content without? Not really. I believe I can speak for average computer users in saying we're not always interested in a "new and better way", just a bit more speed and consistency in the old and familiar. Maybe next time, Apple.
Is Spotlight actually Tunnelvision?
