I think Sony is way too obsessed with size.....

I am looking at the RX1, it would seem to be the ideal camera if it

1) Had a EVF
2) Had interchangeable lenses

Both of these would add size to the camera. IMHO I think Sony chose not to was to keep the size down.

The new pancake zoom for the NEX is another example. I would have much rather had a high quality f2.8 lens for the NEX.

Miniaturization has it's downsize too and Sony looks like smaller is better is Sony's mantra.
