And if you think Apple has been on top since 11 years ago since the original iPod or iMac. You should rethink and see that actually iPod popularity today is declining so fast now, and ironically it's being eaten alive by its own maker. No more hot events for iPod classic, shuffle and so on. It's all about iOS nowadays.
The only heartbeat sign from iPod today is iPod Touch, which actually almost left out with outdated A4 chip to keep them barely alive, and iPod Nano which receive almost nothing but minor UI tweak.
