I've read some pretty iPod defensive articles on the Zune and I've read some pro Zune articles.
It's easy to point your finger at the Zune and laugh - too easy since it's such a big target. Of course, we all laughed at Windows 1.0 in 1985, 18 months after the first Mac and two years after the Lisa (Lisa was the first commercial computer with a GUI). But, who was laughing when Windows 95 shipped?
Obviously, the key for Apple is to make today's iPod obsolete with tomorrow's iPod and to keep putting distance between the iPod and Zune while learning from the Zune's successes and failures.
