Every bit of a DSLR
Some of the features I like 
Color space Ia (sRGB)
II (Adobe RGB)
IIIa (sRGB - more green for colourful landscapes)
DOF Preview When CPU lens is attached, lens aperture can be stopped
down to value selected by user (A and M modes) or value selected by
camera (Digital Vari-Program, P, and S modes)
New Nikon DX Format CCD imaging sensor features an improved signal
to noise ratio and broader dynamic range that produces 3,008 x
2,000-pixel images with high resolution and superbly sharp
details.
New advanced digital image processor uses next-generation
algorithms to handle all steps of digital image processing and
optimize image quality, while also controlling auto white balance,
auto tone and color control, as well as real-time processes to
diminish digital noise and produce beautiful long exposure
shots.
Accurate white balance achieved by Nikon's acclaimed 3D Color
Matrix Meter with 1,005-pixel for highly precise control over white
balance regardless of lighting conditions. Choose from auto TTL
white balance, six different manual modes, or preset white balance.
White balance bracketing is also available.
Continuous shooting at 3 frames per second for a continuous burst
of up to 144 pictures (using JPEG NORMAL - Large settings, and a
SanDisk SDCHF256MB CompactFlash card) thanks to improved buffer
memory handling, faster image processing, increased memory card
access speed and greater system bus bandwidth. (better than 300D
)
The number of continuous shots possible in a single burst may be
fewer depending on the type of CF card used.
Ultra-short shutter time lag is hardly noticeable and unrivalled in
its class.
Immediate power-up has the D70 ready to take pictures before your
finger can reach the shutter button.
High performance System LSI uses next-generation programming to
greatly increase the speed of all processing and writing
operations. This includes vastly improved recording times for
compressed NEF (Nikon Electronic Format) files, the inclusion of a
simultaneous NEF + JPEG file save setting, and real-time processes
that diminish digital noise in long exposure shots.
And some I dont 
The D70 has a standard Nikon hot-shoe which supports a wide range
of Nikon Speedlights including the new SB-800 and SB-600, these new
flashes support the Nikon i-TTL flash metering protocol.
One thing the D70 doesn't support
is D-TTL metering.
Some interesting stuff
Shutter Release Sound
In all of our digital SLR reviews we now provide a sound recording
of a continuous burst of shots. You can download the recording
(click here - 1,284 KB MP3) of the Nikon D70 shooting continuously
for 20 seconds followed by the Canon EOS 300D shooting continuously
for 20 seconds. Both cameras were set to manual focus, a shutter
speed faster than 1/250 sec and aimed at a static subject. Image
quality was set to six megapixels JPEG Fine on both cameras. The CF
card used was a SanDisk Ultra II 1 GB (Type I).
The primary difference between the way these two cameras buffer is
that the D70 buffers the compressed JPEG file, the EOS 300D buffers
the RAW data from the sensor. This means that using a lower JPEG
quality or smaller image size on the D70 would provide even more
images in a single burst at 3 fps. Both cameras allow you to keep
your finger on the shutter release and will take as soon as enough
buffer space is available for the next shot.
As you can see from the waveforms below (which represent twenty
seconds for each camera) the D70 manages 44 frames in 20 seconds,
the EOS 300D just 23. More importantly the D70 shoots the first 17
of those frames at the full 3 frames per second, the EOS 300D
managing only 4 frames at its slower 2.5 frames per second. Kudos
Nikon.
Highlights (note the blinking areas aren't necessarily completely
overexposed but are 'near')
NIKON RULES!!!!!
