You are too critical. I have written instructions for computer software and handled the tech support calls (my own product). You'd be surprised. What is obvious to you is not obvious to others, particularly if they did not design the product.
I am not mechanically oriented, so I find assembling stuff to be frustrating and annoying. Nothing is obvious to me when it comes to screwing parts together. Therefore, I'd rather have too much i than too little as far as information goes.
If you read the threads on this list, you'd be surprised that the company is still in business or that anyone uses their products. The manual is terrible, automatic ISO isn't implemented, the price is too high, the image quality isn't as good as the Nikon equivalent, its the same old sensor, why isn't 40mp, this isn't right, blah blah blah. And except for field testers and carefully crafted promo photos from Canon, nobody has really seen images that average photographers take with the camera on a day-to-day basis.
Bottom line: All of these cameras are marvels and can be used to make great photographs, assuming they are in the right hands.
