Very detailed sound, even with Creative EP630 headphones (I don't know whether the synergy was intentional -- you would think it would be, though). Especially good so far on guitars, particularly acoustic. It seems to me that it drives the EP630s more easily than it drives Etymotics ER6i's (which sound even more detailed, though, obviously) or Sennheiser PX100's, but I just need to turn up the volume a bit when I use the Etymotics or the Sennheisers. Still early though, so I haven't learned the best combinations of music and 'phones yet (minimum 192kbps MP3s).
Nice shape, size and "feel," and dead simple to operate (even without looking at the player). Very pocketable -- almost the exact same size as my keyless entry remote for my car. Too soon to tell about battery life.
Now that I think about it, if Creative were to bundle this with the EP630s, they could charge a few dollars more and have a major hit on their hands ... but even with buying them separately, it's a very nice minimalist "value" rig. And as I said, I'm still trying out different 'phones with it (so far I'm using it at the office, where I generally use the EP630 canal phones for the most part).
The price is still the most distinctive feature (and an exceptional feature, at that), but the performance, combined with the price, makes for an excellent value if all you want is to play music either randomly or by folder.
