You know, you have many choices...

I've heard good things about the Ricoh GR and yes, it is pocketable. Do you want a pocketable camera with a large sensor - like the APS-C size in the Samsung NX series? If that is the case, then you have fewer choices available to you - and they may not be so pocketable. But the GR is nice - but remember, it has a fixed lens. Another camera you should look into is the X100 series from Fujifilm - but they are a tad larger (maybe not pocketable unless you have very big pockets (like in a coat).
Now if you don't mind a smaller sensor, there are several really outstanding pocket cameras (not made anymore - but you can still get them new on eBay). The ones I'll recommend below I own and have used for a few years. They are fantastic 12 MP cameras with great image quality capabilities.
They are the following:
Nikon P330 - sold here on US eBay:

The P330 is a higher end enthusiast model. Yes, it has a smaller 1/1.7" sensor - but it has lots of options and shoots RAW also. I love its color tonality and it fits perfectly in a pocket. It is a great "take it anywhere with you" camera. It has very good dynamic range for such a small camera (in RAW).
Here are a few samples taken with the P330 (all shot in RAW mode):



Other cameras in this genre are the Fuji XF1, or XQ1, or XQ2 (all are 12 MP)'s - and are about the same size as the Nikon P330 shown above. They have a larger 2/3" sensor (which is just a step below the 1" sensor) and have RAW capabilities. These 3 cameras are known for their outstanding dynamic range due to the sensors used. At times, I've managed to get DSLR-like results when using these cameras.
Here they are on US eBay:

Here are some quick samples from my XF1:



And my last recommendation is from Samsung - yes, I'm talking about the Samsung EX2F which I fell in love with several years ago. They are harder to find because owners are keeping them. You can still get them new on eBay, but they are selling for near what they cost in the first place. This camera is built like a small tank and takes outstanding photos - especially in RAW mode.

And some photos taken with this EX2F:





Like I said - you have many choices if you include sensors of all sizes. I did not comment on the Sony cameras because I don't own any of those.
