The S9 rocks
The simple fact is, the S9 has WAY better sound quality than the iPod can hold a candle to, and this should be easy to detect, it is that much better!
The AMOLED screen is simply awesome .
One thing i didnt see mention of was its 55 hour battery life for audio or 11 hours for video - crazily good.
Personally, the Touch I would never buy, as i have an iphone. Listen to it though, its SO poor! It does work well as my Sonos controller though ;0)
Clearly its horses for courses, but if you value sound quality, above all else, and enjoy movie playback, this is the daddy!
