To me a currency is here to make my life easier. After years of travelling, I no longer have any sentimentality for the ' pound ', or anything else where sentimentality over rules practicallity.
I personally do not think the UK will adopt the euro for a long long time, if ever. To be truthful I could not care less, and nor I suspect does the majority on mainland Europe. If the UK is happier keeping the pound, then thats cool as well. It might turn out to be the right thing, who knows.
All I know is that my life is a lot easier with one currency here. Living on the border of France, and not too far away from Germany and Holland.
It is a new currency and for the most part stable, defying the doom and gloom merchants that wanted to see it fall.
The queens head could be shown on one side of a euro coin by the way. The Belgian euro for example shows the kings head.
