Is an upgrade from Lumix G3 viable for a noob photograhper?

Wow, so many great replies. Thank you all, I don't know where to start.

Firstly, the thing that really holds me back is money. The prices of the cameras in Poland as it seems are slightly higher than the figures some of you have quoted. However, what makes the real difference is the value of money, the gap between costs of living and cost of commodities such as a camera (the gap is brutal). With my current income, I can afford a change of equipment, say, every three years and I want the best value for my money.

I have visited a camera store today and had the opportunity to check how the cameras feel. Upon return, I have been surprised to read rambling robin's post and the issue he has with the body: the strap mount does dig into my hand. This is a huge disappointment, because (if I decide to get a new camera) I was leaning towards getting the Oly for its looks and size. The GX7 on the other hand, was just... spectacular. While I'm not fully sold on its looks, I have never, ever experienced anything like it: it fits like a glove, so to speak. It also is significantly cheaper (a quarter of the Oly's price).

When it comes to glasses, the 60mm macro is my dream, but its price tag is steep. I'm using a Raynox macro converter for my macro purposes and I'm pretty satisfied with the results (well, I have to be, as I can't afford a proper macro lens :D). Also, the thing that really holds me back is that I can compensate for all the camera's shortcomings (i.e. low light situations) with an additional effort to carry a tripod.

I'll wait with the decision for now. First, I'll try to figure how much can I get for my G3. Then I might wait for the G7. I like the looks, from the previews I've read it seems like a great camera, the only drawback is the lack of inbuilt stabilisation. Also, I can hope that the release of the G7 will result in a slightly lower of the GX7.
