Well, I like SLRs. Not so sure about your analogy. Regardless, comparing a full-frame mirrorless camera with a single fixed lens against a full-frame camera with no lens but arbitrary/huge selection of lenses for .. roughly the same price?
I think it's important - nay essential - for digital technology to go through this. I'm not really in a position to push it along my own money but hey, it's going to happen anyway.
