Hmm, not at that angle. Is it smaller than the Oly?
Any chance of a side view comparison with the G10/11?
A comparison with the LX3 would be nice too.
I think the GF1 is slightly smaller than the E-P1, but only slightly.
The biggest difference with the M43's compared to say a G11 is the lens size.
On the G11, the lens fits into the body. Obviously on the M43's this sticks out, so to compare the two you need to decide what lens you would like to compare.
If you are talking about comparing the zoom lenses, then this is a useful page, that compares the size of the Oly zoom lens (14-42) with the Panasonic (14-45):

As you'll see, this is where the Oly has the advantage with regards to size, although the review states that they believe the design is optimised for sze rather than quality (although doesn't get a bad review).
With the pancake lenses attached, these are very small:

I would guess if you compared the GF1 (with 20/1.7) with the G11 there wouldn't be a lot of difference. But the GF1 with the 14-45 & EVF the difference would be a lot bigger.
These cameras are not really compact size and yet they are not really SLR size (and the options can really change the size of the camera).
One of the problems with most of the reviews I've seen is that they are either compared to compacts (and the reviewers complain about the size), or dSLR's (and the reviewers complain about the features: viewfinder, AF speed etc).
I guess this is inevitable until more of these type (or EVIL) cameras come to market, so that they can be compared against their piers. It's not just reviewers either - the people at work who have played with my E-P1 also say the same. Once you get out of that mindset that it's not a dSLR or Compact these camera make much more sense. The problem is, unlike APS-C vs FF, the prices of these M43's cameras are high compared to both APS-C dSLRs and Compacts.
I would say, if you are wanting to compare the size of the GF1 with a compact, the GF1 will be too big.
For me, the biggest difference between the E-P1 and my dSLR, is that I can leave the E-P1 hanging around my neck all day without it bothering me. It's not really going to fit in my pocket like a compact, but it will give 'almost dSLR quality' (figure of speech).
My wife thinks the E-P1 is too large (and wants me to sell it), but I think the IQ quality of the compacts that she would find acceptable regarding size, not good enough to leave my dSLR at home.
