The higher resolution and better JPEG engine of the E-PL1 puts the baby Nikon to shame - with the Olympus trumping the DSLR in every respect. The Nikon D3000 isn't here because it offers class-leading image quality but because its feature set is most closely comparable to the E-PL1, even so the difference is dramatic.
