Zen X-fi vs Zen X-fi Stle --> WHICH ONE IS BETTER?

[Pepsi]

Hi,
Im from AUS and is looking to get a new creative mp3 for sound quality

Right now, the 16 GB Zen X-fi STYLE is very similar priced to the older Zen X-fi model ( older one is sttill slightly more expensive)

I need to know which one is better overall in terms of sound quality or are they the same? and it functions? why is the older version still slightly more expensive I really care about the sound quality thats why im not getting an ipod

and does it have an automatic shut down timer when i go to sleep (eg. 60mins later of listening) ??

I need to purchase one very soon.. please answer me... i been spending around 7hours + goggling trying to find a comparison between the two model before i buy it.. but cannot find it so i decide to finally post!

ultimately, is the new ZEN X-fi style an inferior product compared to the older therefore i should spent a bit more for the older model instead??

plus the white new zen style x-fi looks cute!

EDIT: Sorryy for the wrong tittle spelling, its meant to be STYLE!

Thanks
Jen
