Cowon just rolled out a beta of a fairly substantial firmware update to the S9. A list of the added and improved functions can be found here along with a download link. The important updates to note are the additions of widgets and the pitch correction on the video playback. These are noteworthy since these are some features the Samsung P3 already has.
I have been carrying both the Cowon S9 and the Samsung P3 for the last few months and they are both worthy opponents on features and on quality. Though personally I found that I use the P3 more than the S9 mainly due to the UI; the P3 is much more organized and intuitive. Though, with the addition of the widgets on the S9 has made the home screen even more cumbersome, just from the few hours I have been using it. The problem is the S9’s widget screen is a toggle, widgets or icons, where as the P3 mashes both icons and widgets on multiple “desktops” you can flip though. But I digress, once both firmware’s become more stable look for a P3 vs S9 throwdown.
