Viewfinder
The optical viewfinder on the Nikon Coolpix P6000 sits just above the LCD display on the back. A viewfinder can be useful to save battery or if the glare of lights is making the LCD ineligible or if your just a traditionalist and prefer it. The viewfinder is not digital, so we've got actual glass here, which means you should not expect to see any overlays or other information when using the viewfinder.

The optical viewfinder can save you battery power.
LCD Screen
The 2.7-inch LCD display on the Canon PowerShot G10 is reasonably sized, just a bit smaller than the 3-inch display on the Canon G10. Unfortunately the pixel count is not very impressive, just a pedestrian 230,000 pixels, half as many as the G10.

The 2.7-inch LCD display is smaller and has a lower resolution than the Canon G10's.
Flash
The Canon PowerShot G10 flash rises up out of the top of the camera to the right of the lens when looking from the front. The pop-up action results in a flash that sits further away from the lens than the typical point-and-shoot, which should help you get slightly better lighting and reduce red-eye when using the built-in flash. If you prefer to use your own flash the P6000 also sports a hot shoe directly above the lens on the top.

The pop-up flash disappears when you're not using it.
Lens
The Nikon Coolpix P6000 has a 6.0-24.0mm f/2.7-5.9 lens with a 4x optical zoom. This is comparable to the Canon G10, with the latter sporting a slightly better focal length and slightly wider aperture at the tele end. As with the G10 you can also add a lens adapter to the P6000.

The retractable lens keeps the P6000 compact, but we wish it had more than 4x optical zoom.
Connections
The Nikon Coolpix P6000 has a DC In and Mini USB port on the right side underneath a tethered rubber cover. The Mini USB port handles both data connections and A/V Out. The only other port on the device is the Ethernet port found on the bottom, once again protected by a tethered rubber cover.
The power and Mini USB ports are on the right side.
Battery
The Nikon Coolpix P6000 uses a proprietary battery. Nikon estimates that you can capture 260 photos on a full charge. The battery can be found in the compartment found by opening the door on the bottom, it sits right next to the memory card slot.
The battery and SDHC card slot are both found on the bottom.
Memory
The P6000 support SDHC cards, which have a current maximum capacity of 32GB. The memory card slot is found right next to the battery under the door on the bottom of the camera.
Other Features
One of the Nikon Coolpix P6000's much talked about new features is built-in GPS. We did not have an opportunity to use the GPS, but the idea is simple. Turn the GPS on and any photo you take will automatically be tagged with location information. This is something that many people have been doing by merging GPS information with their photos, we'll be interested to see how a built-in solution compares. In particular the sensitivity, speed and battery impact of the GPS functionality will be in question.
GPS is nice, but we still don't know how much it will impact battery life.
