So I bought the D5100, but...

I ended up buying the D5100 ( as many of you know, my wife and I had twins) and sold my EPL1 and 20 prime - now I am a bit unsure of my decision: the Olympus JPEGs are still worlds better than the D5100 even though the D5100 sports an excellant sensor and the Olympus images are crisper to my eyes. So with a window of opportunity still available I am pondering sending the D5100 back and getting another EPL1 or the EPL2.....thoughts ?
