Ah, but for most of us photographic hobbyists, process is part of what attracts us to photography and 'junk' cameras often require more process in order to produce good final images. By and large, Keith's Nikon D700 will produce a sharply focused, accurately exposed image of anything he points it at, without any special effort on his part (switch on, take off lens cap... errr, that's it); the same is obviously not true of any camera which is manually focused and requires exposure to be set manually. This requires some thought about what we are trying to achieve and how we want to achieve it; subliminally, I suspect it also means we pay more attention to framing, perspective and a host of other things too.
I'd go further, and say that this is one of the attractions of rangefinders over SLRs. In addition to setting exposure and focus, an RF camera also introduces difficulty over framing. It isn't insuperable, but it's there and it forces us to think about what we're doing that little bit more.
So, it doesn't surprise me that Keith takes more interesting pictures with 'junk' cameras than with his D700. I think I'm the same.
