More E-P1 sample images at Imaging Resource
Imaging Resource is working hard to break the record for sample pictures included in a digital camera review :-) They have added some new samples to their mega E-P1 pictures page, including indoor portrait shots and files converted using the cult-favorite dcraw utility. To locate the former, just page up/down until you see the portraits. To locate the latter, use your browser's search function (CTRL-D for Firefaux) and search for "DCR".
And speaking of dcraw, here is an interview with its creator at dpreview.
