I'm definitely warming up to getting one, in some ways the fixed lens is reassuring, that I won't be after another one in a few months, and it will force me to be more imaginative.
I think if I walk into a shop in SF and there is one to walk away with, it will be hard to resist.
One other thing to consider. You said The GF670 is much cheaper in the US than it is in the UK. If that's the case and you have enough spare cash available then why not just buy it, try it and if you decide you don't like it you can resell it in the UK for whatever you paid or close to it.
