Own non-DAB version
I have the non-DAB version of this player and I am very pleased with it.
Killer for me is the fantastic SDHC support. Previous player was the Creative ZEN 8GB with atrocious SD support - you had to browse the card separately and it would stop playing when you browsed elsewhere.
Also handy is the fact that the storage is available as a simple USB-storage device meaning it will work on any OS you fancy. You can even upgrade the firmware from the USB storage interface. Again, contrasting with the ZEN, you are free from nasty proprietary (slow, barely working) interfaces like MTP.
Can't speak for the video/radio support as I don't use them, but something to keep in mind is that (the version I have at least) has no support for mpeg4 b-frames so even if your video is a playable resolution/codec you may get choppy playback. I plan to release a FUSE file system soon for iPods, Creatives, Cowons etc which will take care of all this for all you *nix users. Keep an eye ;)
