Nikon D100 Digital SLR

First read Digital Photography Review's excellent comprehensive review of the D100. Then here are my reactions after six months of using the D100. These are all relative to the Nikon F100, which I used and loved for years.

Pros

The D100 works and feels like a high-end Nikon SLR.
The physical UI is excellent. Controls are well placed and easy to understand. It is in some respects an improvement on the F100 (which is awesomely designed).
It's light.
On-board software is great. Menus are very usable.
No noticeable shutter lag.
Quieter shutter than an F100.
Pop-up flash is very handy.

Cons

Nikon made several improvements to their software suite (Nikon View and Nikon Capture) over the last six months, turning it from unusable to acceptable. Nikon Capture is better than Nikon View, but costs ~$100. (If you're a Photoshop user, I highly recommend Adobe's Digital Camera Raw plugin. It too costs ~$100 and vastly improves the D100 workflow.)
It's not as hefty as the F100, which is a little surprising when you first handle it. It isn't clad in metal. I have no idea if this means it is less durable, but I'm definitely inclined to treat it more carefully. However, I've had exactly no physical problems with the camera in six months.
Autofocus is a little slower and louder than the F100. In this respect, it feels more like an N80.
NEF compression is too slow to use.
No FireWire connection.
Old flashes don't support DTTL mode. Need to have one of the new DX flashes (SB-80DX or SB-50DX) to take maximum advantage of the flash system.
1.5x focal length multiplier means all your lenses are redefined. I miss my 20 mm.

Usage Notes

The little popup flash is fairly stinky, but still nice to have around. It's a little too hot for a fill flash by default. It is much less subtle than the F100 and SB-28 combo by default. Using the flash output compensation to adjust it down by a stop or more is much more to my liking.
NEF compression seems to be on by default and you can't see this without using the menus. Turning it off speeds up processing time significantly.
Battery life is amazingly good.

Bottom Line

It is more like a digital N80 than a digital F100, but the N80 is a pretty good camera. The D100 is very much what I've been waiting for all these years: a real Nikon SLR for around $2k that just happens to be digital. It rocks.
