Sell my XSI for Olympus PEN ?

I have the itch, I had the PEN years ago and really loved it. It's very hard to quantify, but the PEN gave better skin tones and better OOC JPEGs over my XSI, though the XSI rendering seems a little better (maybe the DOF is to blame). I might keep the XSI and just get the PEN as camera number 2, but I often have trouble justifying the cost of keeping two bodies.

I really don't like processing RAW files these days so I am looking for a high quality interchangeable lens body with the best JPEGs.

Thoughts ?

I prefer optical finders, but if you don't mind using the back screen, go for it.
