I don't like the RX100 autofocus. . .

I agree... I wouldn't say it's terrible, but I think that you're referring to the AF's inability to achieve focus on low contrast areas with only fine detail. I've shot with it for about two days now and noticed on several occasions that you need to put a hard line in the box for the AF's contrast detection to work. Has any one else that ACTUALLY HAS one of these cameras noticed the same?
