Don't start on that!

I'm, normally, very pro-European standardisation on technical things.
Certainly, when I was working for BP, the pan-European standardisation
on lots of things made my life (as European IT Manager for one of its
subsidiaries) a lot easier!

However, on the whole question of the Euro-socket, I'm completely of the
view that we shouldn't adopt it for all the normal reasons!

Regards,

Mark

Keeping to the HA theme, at least directives such as the Low Voltage
directive mean that I now can buy and legally use HA equipment sold in
Belgium, for instance, in the UK.

The main purpose of these directives is to drive costs to consumers
down,
and remove barriers to entry for smaller enterprises making equipment
(really!), and allow cross-boarder purchasing

Have to confess some self interest here, though, as I am involved in a
European research consortium for standardisation - anyone interested in
the
5th or 6th IST framework, just ask

If we can just get some agreement on the power connectors on the
wall....
