...and I'm a big fan of the Cowon range. If they do get good OGG/FLAC support, I might be looking at that to replace my loverly D2 (which has 8GB onboard + 16GB SDHC).
The drawbacks with the D2 at present are a slightly flaky database when it comes to indexing the OGG files and really, the device is overpriced - they tend to cost more than similar Apple offerings, and are less styley. Although they sound fabulous - I had great sound out of the box with the D2, and gave up on getting anything good out of the iPod, even with Rockbox and every kind of sound tweak tweaked. The D2 also takes forever to boot when the database needs updating, and it irks me that there isn't a setting for it to automatically resume the music after starting up (it does resume from the track you're playing, but you need to select the Music option and then hit Play).
Assuming the Sandisk offering sounds as good a Cowon beastie, the price is definitely right, it doesn't look fugly, so it'd definitely be an option worth looking into.
