I don't need an RX100!

I don't need an RX100? I keep trying to tell myself why my LX5 is good enough and how the RX100 isn't that much of an upgrade and it's just looking attractive because she's the new girl in town. I think I might be starting to fail. Anyone want to help convince me? My wife will bake you some internet cookies or something for saving me $650

So far I am thinking:

RX100 has no hotshoe
Only 28mm wide angle and no true multi aspect
slow telephoto
no dynamic B&W
Poor RAW support.
