Thing is, perhaps if having one of each type of Leica isn't a financial problem, you can have the best of both worlds? And you can even use the same lenses!
Considering I've been using an iPad camera these past couple of day, I think photography can become far too intellectualised unless it's for earning one's crust. The single, really positive aspect of that device as camera, is the viewfinder. So generous and close to what you think you may be getting. But the ergonomics are truly dreadful! I kept switching on the video just by tuning the thing from horizontal to vertical. And banging the screen to make the exposure really is madness. At least a little button on the side, please!
