Overall conclusion

The D300S isn't nearly as significant a step forward for Nikon as the D300 was but that in part is a testament to how good the D300 was. When we reviewed it, Phil stressed how difficult he'd found it to find things to criticize so it's not surprising that Nikon has found it hard to know what to improve. But there are improvements and ones that will be welcomed by certain sections of the photographic community. The ability to shoot movies, although seemingly gimmicky, does appear to be a benefit both in terms of creative options and commercial potential, so shouldn't be dismissed. The addition of a second card slot and the useful ways in which it can be used also considerably increase the flexibility of the camera.
Image Quality

With a 12 megapixel sensor, it would be easy to think of the D300S as being a touch out-of-date. However, that would be to miss the point, as the difference between 18 megapixels and 12 (20% in each direction), is only of value in certain specific circumstance, especially when you're talking about 12 very well captured and processed megapixels. And that's what you get with the D300S - dependable, quality images which it's very hard to find fault with. The JPEGs may be a little softer than we'd choose but they respond well to the sharpening being pushed up a notch, so it's just a matter of tuning them to suit your purposes. Processing from raw brings even better results.
Handling

Handling is one of the places that the D300S really shines - both its ergonomics and build quality are first class. Although it's easy to initially be intimidated by the sheer number of external controls, you soon become familiar with them and find yourself glad of them. Then, thanks to the high level of customization, you can add other features you want direct access to onto the user-definable function buttons on the front of the camera. Furthermore, if you're unfamiliar with the Nikon way of working (dials and indicators all have positive on the left and negative on the right), the behavior of both can be switched so that it more close resembles the cameras you're used to.

Although the button changes over the D300 are subtle, they make a surprising difference, not least in terms of making access to video really straightforward. There isn't universal agreement here about the positioning of the buttons on the camera's left shoulder (White Balance, ISO and Image Quality), but that's about the only point of contention, despite us all being familiar with different brands.
The final word

The D300S is not the standout product that its predecessor was and unless you find your clients are clamoring for video footage, we can't see much need for existing owners to upgrade. But that shouldn't take away from an absolutely excellent product - a gently polished and refined update of a product that we considered a benchmark when it was released. The EOS 7D may prevent anyone with a foot in the Canon camp from contemplating defection but unless you desperately need that camera's higher resolution, it's hard to overlook the appeal of the Nikon.
