Sue, to be clear, you're talking only about the LCD display on the back and not the pictures it takes right?
I've tried the HX50V and I am very impressed by it. You will not get a better superzoom in a package that small. It's only a little bigger than the RX100 and has a 30X optical zoom. The digital clearzoom works really well. I used to downplay digital zoom in camera saying that it's a waste since you can crop in post and make it look much better. The HX50V shut me up about that. It's doing something special. It's so good that if someone told me that the HX50V was a 60X optical zoom camera I would believe it. The day I tried it I considered replacing my RX100 with one. As an all around travel camera it's very appealing. But in the end, the IQ coming out of the RX100 is so much better than the HX50V. It's a great superzoom P&S camera, but it is still a P&S camera with P&S camera IQ.
