I was wondering if anybody had any thoughts on the new line of Vixias. I was saving my pennies for a S20 but now with the new ones -G10, S30, M41/40/400 - I'm not sure if I should start looking at these, too. I've read the specs but am not that into video so a lot of it goes in one eye and out the other without much comprehension. Basically, I'm looking for an imac compatable, hd, sd-card camera with decent low light shooting and optical zoom to shoot family stuff, nothing professional. The S20 seemed fine for me but does anyone know if these new ones' video/audio quality would blow the older ones away. Basically, any thoughts on the new line would be appreciated.
