What does $2000 more get me with the RX1 that I don't get with the EPL5?

Some very thoughtful comments and responses to my initial question. Thanks all. And to pcb-dpr, whatever it is you think I need to get over, I'll try to comply. I promise. As to SONY selling "a ton' of them, let's not hold our breath. The next one with the built in viewfinder and interchangeable lenses will sell by the ton. i think this one will sell by the ounce.
