i have changed my x20 into an rx100 and it was'nt painful. Itried the x20 for 2 days but could not get on with it as i wanted a truly pocketable top quality compact and good image quality. I already own an x100 & xe 1 with the 18-55 & the 35 so am well catered for in that area...but there are times when i need something smaller, which is an s95, but felt that i needed something morrecent hence the x20..but it is not truly pocketable...so i changed it for the rx100 nad no regrets. i did have an rx briefly at the beginning of the year so i know the ins and outs and more importantly the picture quality. Now i just need some decent weather...
