Well it depends on what you are coming from and where you wish to go....

Summary: Well I tried. Yes lighter than my D7000 with 18-200 and the super zoom "fun", but the electronic viewfinder not for me. Fuzzy once you are used to a pentaprism. The speed was just OK and did not enjoy having to choose burst mode to capture moving targets. I guess if cost is an issue and DSLR's are a bit much for you, this could be a good choice vs pocketable cameras. obviously many love it... if its your first step up to "more" this might well be your camera.
Summary: Fuji has several design flaws caused by cheap manufacturing practices. I myself and several friends have had the exact same failure on the power switch, that makes the camera useless. When under warranty Fuji will fix it if you pay for shipping, but then you have paid over full price for a refurbished item. A say this with disgust, because I had less than fifty photos on mine when it broke; the technician said it was a common problem and an easy fix.
Disappointed with the XS1 and especially Customer Support
20 July 2013
Summary: Ok, I did months of research to find out which camera would give me pretty much what I wanted, and if it didn't I would learn to work with it. I chose the X-S1. It had to be ordered from another related store, as the NH camera store didn't have one available. The store owner indicated that he was very happy with Fujifilm's customer service and they go out of the way to make their customers happy.
Summary: I was looking for a travel camera that would be more capable than a pocket camera but lighter, smaller, and less awkward than a DSLR kit. I was intrigued by the X-S1's huge zoom ratio, the separate buttons for frequently adjusted settings, light weight and smaller size compared to a DSLR, and the rave reviews for the X-100. I'd hoped for some or most of the X-100's claimed picture quality. Long story short, I've just sent the camera back to Amazon.
Summary: The Good: Better image quality, better build, good feature set The Bad: Specular highlight distortion (orbs - white blobs), sagging lens that is thrown out of focus, blue flare in lens. Check out [...] for sample images and reviews.
Summary: Lens droop is when the barrel droops down due to the weight of the lens, or the zoom slowly unwinds of it's own accord when the camera is held at at downwards angle for the same reason. I have this problem on mine & I contacted Fuji with the expectation of getting it fixed under the warranty, their reply was "The X-S1 lenses do droop when held at an angle especially with the lens hood attached. We regret this is not considered to be a fault with the camera.
Summary: We bought the XS-1 based on the reccommendations of a couple of friends who achieve good results. However, we found it very difficult to set up and we did not achieve results close to those we can get with a DSLR. We also did not like the electronic view finder. I could not use the view finder when I was wearing prescription polarized sun glasses.
Summary: I purchased this camera instead of buying a Nikon d5100 + 3 lenses thinking it would be easier to carry one camera around. I was expecting to lose some sharpness especially at the high end. The first thing I noticed about the X-S1 was it's awkwardness! It didn't feel right to me - It was too large and too heavy, I might as well have been carrying a small bag of lenses around anyway!
Summary: Bilder werden selbst bei Zimmerbeleuchtung Super. Leider wackelt das Ausgefahrene Objektiv wie ein Kuhschwanz herum. Bei einer Videoaufzeichnung hängte sich die Cam auf. Das konnte ich erst feststellen als ich das Video beenden wollte. Das Videomodus lies sich nicht stoppen und die Cam konnte auch nicht ausgeschalten werden. Erst das entfernen des Akkus lößte das Problem. Ein Video wurde leider nicht aufgenommen.
Summary: Non so che dire, mi dispiace invertire il trend delle rece di questa macchina ma io mi ci sono trovato proprio male, tant'è che l'ho venduta. AF lentissimo e molte (troppe) volte non riesce; qualità d'immagine scarsa un pò a tutte le focali e ridicola in tele, il sensore che dovrebbe riconoscere l'uso del mirino ottico fa un pò come gli pare, lentezza generale operativa, scatta in RAW ma Aperture (diffusissimo, non parlo di un software vatteloapesca) non li legge.
