Design your ideal camera (just for fun)?

If you could take the best qualities from various camera systems and create your ideal camera, what would it be like? Throw logic to the wind here, it's not a serious question.

For me, it would actually be quite simple: the responsiveness, autofocus speed, battery life and high ISO performance of the Nikon D3s (or the D4s, although I've only briefly played with one… Holy hell, it's fast), the pixel acuity and resolution of the Sigma DP Merrills, and the handling of a Leica rangefinder.

This combination is of course totally absurd, not to mention impossible, but tell me it's not fun to imagine!

Let's hear your concoctions.
