Rob.....I could go on for pages here on my love of my X20, but I will try to be brief. It will fit in a jacket pocket but I usually carry mine in my hand in this case....it is a wonderful and tough well made case.
The X20 is my go to camera when I walk out the door, and is very capable with more controls and settings than some full size cameras. The first thing that will impress is the very solid metal build quality , with machined knobs and a very solid feel in your hands that beckon you to use it and use it often!
There are tons of X20 shots here...like all forums, some good some not so much, but it does give you a good idea of the possibilities, and they are many.

I did a review of mine here some time ago, but the bottom line is that it is a jewel of a camera. If you do get one, be sure you explore all the Fuji settings, like Pro Low Light, which is simply amazing for night or low light shooting hand held. It takes 4 rapid shots, combines them to eliminate shake and noise and gives you a finished in-camera shot in seconds. Beats my K5 by miles!
The OVF is a must for me in the bright Texas sun, and I often use it inside too for portrait type shooting. It is wonderful and clear! The info in the OVF is handy too...you can see exposure and settings before you snap.
I was thrilled with the X10....X20 and will for certain get the X30 if it is anything like the X20. These are fantastic little cameras.
You might check out this thread too.......just for fun!

Best Regards...Any questions I can answer on the X20, PM me and I will do my best!
I still get a little thrill just holding it in my hands!
