Well, just back from holidays to Costa Rica, the nicest place on earth.
Of course, it would happen that on the very last day I get notification of the release of V1.1 of NX300 firmware, which addressed the a number of things I found incredibly frustrating on holidays... Oh well...
It can be found quite easily on the product pages for the various international sites.
I have not much chance to play with it yet, but it seems the focus definitely has been worked on, and they indeed have fixed the problem of the OIS not engaging at times (especially on 60mm macro), but I will go into more detail once I have had a chance to use it more.
Soon I will also stick up some pics from holidays.
