I don't want to spoil it, but I'd be lying if I said the S9's GUI doesn't come across as a poor imitation of the Apple iPod Touch. I know that iPhone and iPod Touch comparisons get thrown around a lot these days, but really, this thing makes thelook original.
Like any Cowon device, the S9's file support and sound quality are probably fantastic, but if it walks and talks like a knock-off, no amount of FLAC compatibility will make you feel better about flashing this thing around.
If the rumors are right, it may be awhile before this Touch contender makes its way stateside. There's still no word on official U.S. pricing, but a Korean press release puts the 4GB S9 at 219,000 won ($150), 8GB for 259,000 won ($178), and 16GB for 309,000 won ($212). Unless you're spending December in Korea, don't expect to see the S9 until 2009.
More photos of the S9 are available on Cowon's S9 product page.
