The modern DSLR, similar to all older film cameras, is designed for stability while shooting. One hand on the vertical plane and one on the horizontal for tracking, up, down, left and right while holding both planes stable. This “can” is just a telescope with a digital P&S optics and a battery holder jammed in between for “AA” batteries. Really? AA batteries are highly surpassed by batteries already in use in DSLR cameras everywhere. There is no stability point and tell me, how many times have we all dropped a drink can out of our hands. This is just like those, even though Coke bottles have “curves” they still get dropped. I one hand my cameras frequently when moving from position to position to shoot via a hand strap. This thing wouldn’t even accomodate that safely.

Not to mention how to use different ranges of optics which need to be changed out for different subjects. If one 8mm-400mm lens could be produced and have top notch superior optics it would have already been made. Interchangable optics are forever needed. 
Innovation and change is not always best and it is exciting to see people thinking outside the box, but this is impractical in the real world of professional photography, sorry to say. But it would make a neat HD camcorder and conversation piece!

In addition I think the button, viewfinder, and LCD layout on both of my Nikons are just a bit bizarre. There’s information there that I rarely need, and the lack of information that I do need.

For instance. I think I should ALWAYS be able to see, ISO, shutter speed and Aperture. I shouldn’t need to  click or hold anything to get see any of those.

It’s basically a camcorder form factor, which is not good IMO, especially not for stills. your elbow has to come up far to high and away from your body. 

Why change something that’s works so well?
