I love playing with my mirrorless camera and lenses, but I'm becoming more and more convinced that it's a risky proposition "investing" in a bunch of expensive camera gear (which traditionally holds it's value better than most gadgets) when computational methods will soon evaporate the advantages of bigger sensors / faster glass.
