Hi Mohd, camera weight is a factor. I have shot with the Nikon D3 with the 24-70 f/2.8 lens, and it is really heavy, my wife can't hold it with one hand.

A DSLR that offers great image quality but is still light and small would be great!

if you think weight is more important than image quality, why you're interested in a DSLR in the first place? a point and shot camera is going to be extremely useful for you since they can be more than 2X lighter than a D3100.

I think by the time you master your photography and feel the limitation of your D3100, there will be another update cycle in Nikon range of cameras, probably you'll be getting the D7100.

I agree, the D3100 is a smaller device which can easily replace any digital camera out there, there is no much potential in the D3100 for the price its offered at. However the D7000 is such a awesome piece of equipment. Im getting the D3100 and probs get the D7000 once I become better at Photographer.

Does anyone think having both is a waste of money? I figure since i will invest in Nikkon lenses I could just get the D7000 body by itself.

OK, I just bought the D7000. I do love it. It is incredibly capable and though larger than the 3100, it's still much smaller than all the big honking Pro cameras. I was going to sell my D3100 but I love that too and nothing fits better in my small hands. So I'm just gong to have to keep it too!
 
Ipatronius (0:37 PM, February 19, 2011)
Don't forget the D-7000 has the command flash ability and IR remote, both lacking in the D-3100. But the smallness and lightness of the D3100 is very significant to me, especially when carrying around while travelling. I may have to keep my 3100 for trips and get a 7000 for taking portraits and use around the home....

lighter means more plastic, I prefer the weight.

I know that The Nikon D7000 is more nicer but to be honest i find the Nikon D3100 more useful because its more lighter and much more cheaper even though i can afford the Nikon D7000 for me Nikon D3100 is MUCH MUCH MUCH better......
