djk - I agree entirely with you on the IEC plugs. After all, we already get a LOT of europlugs and schuko plugs on appliances now. These are fitted with exactly the clip on adaptors you are talking about - I presume you have the same situation in Ireland too. They could make exactly the same thing to convert IEC to schuko, or indeed any other outlet. In fact, Power Connections in the UK do that very thing already - so IEC plug here we come ( I hope ) :-)
