Which POD for the x10?
I use the Ultrapod mini (not the larger Ultrapod II) for my X10, I think it is more versatile than a Pod. In addition to using it as a tripod, I also use it as a pistol grip on the bottom of the camera when using the LCD for framing, plus you can velcro it to a tree, pole, or any other vertical (or horizontal) brace that the velcro strap will fit around. I attached the optional quick release head (the light gray piece) and it can go on/off in seconds, much faster than threading it into the base every time it goes in/out of a pocket.
Here's my X10 with Ultrapod attached:
