They were doing a lot of online comparisons and it's their first 'high end' camera - i.e. they don't know exactly what they want, and from a visual aspect I think they might be happier with the X10 as well. I just wanted to know if there were any specific functional demerits / differences of note I should be looking at.
In fact, I'm pretty sure that the preference for the G12 came from when I lent them my Fuji X100 and they fell in love with the overall form factor + OVF and that the G12 is the closest thing they could find. They didn't mention the X10 - very likely because they don't know about it, and I haven't mentioned it either.
I know the G12 is the most they can stretch to and they were talking about buying it on sale after Christmas. I'd like to surprise them before.
