Over the years we've owned many digital cameras including DSLR, Micro Four Thirds and Point & Shoot. I'd rate my abilities as an advanced armature.
Simply put, the RX100 is the best P&S camera available today, period. Why? It has the best sensor available in a P&S camera and, in terms of image quality, can and does produce results equal to those form DSLR and MFT cameras, simply put the Sony 20MB sensor produces absolutely stunning photos.
The RX100 can be used as s simple P&S camera, just set it to Superior Auto and go to work, you'll love the results. If you're an advanced shooter, the RX100 has a range of manual control that will accommodate any shooting approach you'd like to use, if you want it, it's there. The Zeiss lens is terrific and has a very useful zoom range. Tiered of LCD viewing screens that can't be used in bright sun, well forget it with the RX100, just turn up the brightness and keep shooting.
There isn't much this little, truly pocketable, camera can't do it terms of producing excellent photographic results. In case you haven' guessed, I love this little wonder. And, yes, the menu system has a steep learning curve but that's true for any camera with loads of manual control and flexibility.
