and the iPod can't possibly outsell a Zen
No other tech company in history has demonstrated repeated customer rallies like Apple. It's true that many others do make fatal mistakes. Apple can do what no other electronics company has done in the phone market - extend a mindset of quality into EVERYTHING including user experience, first and foremost.
How many iPod killers does it take to kill an iPod? - answer there hasn't been one, despite the iPod's age. How many people think Apple would shutter it's doors? - an infinite number of those others lacking quality.
Wait and see. That's our only option. Just don't be surprised when you're surprised.
