Aaaaggghhh now looking at buying the rx100. Nit sure what's holding me back. Maybe lack of viewfinder or bokeh questionable?
I have the RX100, its a nice compact.
I think you really need to decide what your needs a priorities are, I think the only real reason to consider the RX100 if you want a camera as small as possible with decent image quality and features.
If being small is your number one priority, the RX100 is a sensible choice, however, if you're not as concerned about size, i think there are many more appropriate options.
If you want good bokeh, at anything other than close up, you are really going to need to look look at wide aperture lenses on largish sensors, ideally at longish focal lengths.
The distance to your subject, and the distance of your subject from the background makes a big difference regarding out of focus backgrounds.
Even a small sensor camera can achieve out of focus backgrounds with close up subjects , or at very long focal lengths (such as superzooms), but in more everyday scenarios you are not going to get much subject separation with a compact.
Everything is a compromise, if you want the best bokeh you might consider a full frame camera with 85mm F1.4 lens, but this combo is expensive and heavy, using your G3 with the Oly 45 F1.8 is a good price/size compromise.
If you are happy with out of focus backgrounds on only relatively close up subjects, and need a super compact option the RX100 or similar might be a good compromise.
