I recommend not being so influenced about that. Neither camera could be considered big, and like pRICE cUBE says, even the entry-level models from Nikon and Canon are smaller than you might imagine.
Small size is a hindrance if the camera forces you to wade through a menu system to change what should have been easily accessible by a dedicated button or knob. If a feature isn't convenient to use, you won't, and it becomes just another point-and-shoot camera to some extent.
The other reason I urge you to not worry too much about size is because when you make the most of any system that takes different lenses you suddenly have more to carry (conceivably) anyway, with an extra lens or two, filters perhaps etc. If you don't see yourself doing that consider getting a larger point-and-shoot instead and don't sweat it.
As to your question, I've not seen either camera but have read about both. The Oly 620 appeals more to me for what it offers. The G1 appeals to me more for what "it stands for."
