Is it worth having a GF1 if you've already got a G1 body. Reason being even though the G1 small, it's still not totally comfy jacket pocket size. I really want something i can take with me when doing nothing more than walking the dog. Also having a HD video on demand when needed would come in handy to. As i already have the 20mm this will permantly stay on the GF1, and the zooms used on the G1 body. So what do you reckon guys.
