The only real difference is the speed, which I feel is a real factor. I have now two 'slow' wide zooms. 18-35 f3.5-4.5 and more recently the 18-105 f3.5-5.6, which I use on the 3100 almost exclusively. I am often looking for those 'extra gears', of opening the lens up to f2.8 or just above.
I was taking some snapshots of my car one evening recently, I tend to take pix at the end of the day. I couldn't get a sharp image due to the low shutter speed I was offered , I tried flash but wasn't happy with the effect. So I HAD to go get the tripod. Some weeks later I realised the VR was turned off, which might have helped but f2.8 would have been my first call because I would have welcomed a shorter DoF
I am probably spoiled by having almost all my lenses f2.8 or faster, when I have to use a slower lens in unfavourable conditions it as annoying, to me anyway. I don't like upping the ISO on the 3100 too much because it has a fine resolution and the noise is horrible, worse than the D200 but I feel the D3100 is worth at least a couple of stops over the D200.
