Well, some people blow their tops when I point out that a Leica is--quantifiably--more complex to reload than an SLR. So we all have our prejudices.

And I don't want to get into a tit-for-tat, really, just point out that not everyone finds Mamiya TLRs awkward to use. And to me, it's different than a Rollei but no better or worse. I'll agree with you that most any TLR with a prism is awkward for any number of reasons; they're optimized for use with a WLF. Then again, so is a Hasselblad, IMHO...
