Fuji x20 v Sony rx100

Few would argue there are tons of cameras that use high quality plastics (D5100, T3i/600D, D5200, D600, 6D, etc).  But this whole discussion about build quality started when with someone laughing at the mention that the X10 is constructed of high quality materials and is one of the better compact for build quality.  Camera build quality and IQ, or lens build quality and IQ are two separate issues that don't have a whole lot to do with on another.

But in general cameras with metal or magnesium alloy sub-frames or lots of metal parts tend to be higher end products in higher price brackets than their lower-end, plastic counterparts.

I'm not even sure what this argument is about anymore.  All I know is that I've owned perhaps a dozen compact, P&S cameras in my lifetime and the Fuji X10, X100, and Ricoh GRD III are the best built, most robust compact cameras I've ever used.  When someone writes "LMFAO" in reference to the X10 build quality, I have to wonder what one earth they are talking about.
