Not being forced to adopt the Euro was the deciding factor for me. I think one of UK's strongest features is its attractiveness as a financial centre. I could only see erosion looming remaining in the EU under the then prevailing circumstances which would have made most of us poorer. Yes it was a bit of a rock and a hard place argument but I now think that whats happened since has made it less relevant although the seemingly insolvable Ireland situation keeps rumbling on. If anyone can explain to me why the North and South becoming one country is such an issue I am all ears.Living in Eurozone I honestly cannot see any problems in doing so....perhaps how the UK residents regarded their membership differently...including not taking the Euro, driving on the wrong side etc etc....
