Design

1.Has a flip-out screen

Nikon D3100
Flip-out screens can be useful for tricky shots.
2.weather-sealed (splashproof)
Nikon D3000
Nikon D3100
The device is protected with extra seals to prevent failures caused by dust, raindrops, and water splashes.
3.weight

536g

455g

We consider a lower weight better because lighter devices are more comfortable to carry. A lower weight is also an advantage for home appliances, as it makes transportation easier, and for many other types of products.
With 100% coverage, you can compose the image correctly when you capture the photo. With less than full coverage, you may have to crop your photos afterward to get them looking perfect.
5.has an optical viewfinder
Nikon D3000
Nikon D3100
An optical viewfinder (or OVF) allows the photographer to compose a shot while seeing exactly what the lens will capture. OVFs have no time lag and require no power - as opposed to electronic viewfinders, which can drain battery life. OVFs are also better in low light situations.
6.Has a hot shoe

A hot shoe can be used to attach an external flash, as well as light meters, viewfinders, rangefinders and other attachments.

Optics

1.sensor size

23.6 x 15.8mm

23.1 x 15.4mm

The larger the sensor the more light the sensor captures yielding in better image quality.
The more focus points the more flexibility in picking which part of the scene to focus on. They also give the image sensor a better probability in identifying the right area of the scene to focus on in more automatic modes.
The number of megapixels determines the resolution of the images captured with the main camera. A higher megapixel count means that the camera is capable of capturing more details. However, the megapixel count is not the only important element determining the quality of an image.
With a higher light sensitivity (ISO level), the sensor absorbs more light. This can be used to capture moving objects using a fast shutter speed, or to take images in low light without using a flash.
Fast continuous shooting is useful for catching action shots.
6.has AF tracking

Nikon D3100
With AF tracking, once you choose the subject and press the shutter release part way down, as the subject moves, the autofocus will follow it. No more out of focus shots.

Videography

A phase-detection autofocus system is faster than a contrast detection autofocus system. Even when recording scenes with a lot of fast movements, the videos are sharp and clear.
When recording movies they stay focussed and sharp.
3.has a 24p cinema mode
