Right. I should make one note: simplicity I do find very attractive, and if this camera had pure and simple operation like an M9, it would be a lot more interesting to me. However, Sony is not about simplicity (other than the fixed lens), and haven't been for decades now, and I know that I would get a camera with many buttons and a menu system with several hundred items, so at this point I lose interest again.
You may not be aware of this but the menu system on the RX1 is patterned after the Alpha, not NEX, cameras and is - apparently - much simplified and has been received well so far by reviewers and owners. The dumbed down NEX interface is gone; now a simple hierarchical menu list has taken its place. In addition, almost every button can be redefined to suit an individual photographer's preference.
As for "many" buttons, given it is an autofocus / manual focus camera, it'll need at least one extra control to select focus mode. The Leica M9 has 12 controls by my reckoning, the new M typ-240 has 14, and the Sony RX1 has 15.
In the case of the Sony, you can redefine the Movie button or disable it completely. Now it has the same number of controls as the new M.
Personally I don't want too few control points just like I don't want too many. One of the flaws of the NEX-5N from my perspective was that it had too few control points (or too few re-definable control points) which forced one to dive into menus more often, although it like many cameras could be configured to minimize menu diving. As almost every control is re-definable on the Sony RX1, it should be possible to tune the operation of the camera to ones preferences.
It looks as if Sony is improving their game in this regard. Proof will be in the using.
