Hi Darren,
I too am looking at the Sony DSC-H1 and contacted Sony who replied that the camera is compatible with Mac OS X (10.4) but that their software was PC compatible only. I have a feeling that loading pictures into iPhoto may be more involved if this is the case. Have you found out any more info or did you go with the Canon? The Canon is attractive also, but I wonder about the shutter speed.
Thanks in advance, MG
