I started my journey into Fuji with the X10, kinda addicted to the X-es haha. Both are excellent cameras.
Sorry, my bad; should have made it clearer and phrased my 4th sentence more clearly. I was comparing low light performance - where the X20 is at a disadvantage when compared to the RX100II. I brought both on oversea trips all the way hence I'm not making a conclusion based on a 10 min playtime at the shops. I kinda struggled with X20 in low light quite often (ok, probably due to my lack of skill too)
In good lighting conditions, nope - the x20 was always more than enough to satisfy my needs. The OVF & info-overlay is by far the best I've used; no complaints - full stop.
again, do try out the RX100II if u decide to get it; go to the Sony at Isetan Wisma Atria

Ergonomics was an issue for me & coupled with the lack of a proper manual zoom ring; if not for these 2 reasons , the Sony would have been a keeper.
If Fuji can produce a camera with the low light/high ISO performance of the RX100II and keep to X20's body/button layout design, that to me will be close to perfection. (k, i'm dreaming i know)
