Hi there (thanks for your comments on the Canon site as well). I think I've decided that I can manage without zooming - I've been used to it with my old Lumix anyway. It doesn't always look great if there's too much zooming going on anyway! It's a lot to ask of a small camera and at the moment I'm just so happy with the clarity.
I might change my mind after I've taken it to a gig but I'm hopeful it will be fine for what I want. I've put one of my first videos on Youtube from a work do and it seems not bad for a low light room.

I'll post some pics once I've got enough to select my best ones from!
Thanks again and to Chris P as well. These forums have been really useful giving info (even if I was tearing my hair out at one point trying what to decide!!! :-))
