What kind of menu do you want? There is a lot of information and settings that have to be presented to the use
There really isn't. Not on the camera itself anyway. 95% of the menu setting never get touched or get set once and never touched again so why do they need to be in a crappy interface at all?
Professional photographers change their settings regularly. So do advanced hobbyists. Nobody else needs a DSLR, so this is a complete non-problem. If you find DSLR settings confusing, you would almost certainly do just fine with a super zoom compact.
You are going to interface the camera with a computer at some point so why not offload the menus for the rarely/never used settings to a PC or tablet?
Because I need to be able to change the setting quickly, and also while holding the camera with both hands. I might be on a moving vehicle. I might be in a constricted space where I can't let the camera go and let it hang on its strap. I might need to change the setting faster than I can get my phone out of my pocket.
