Well I have yet to interrogate myself as to what I believe regarding fuses, linear vs switched power supplies etc.

But what I do believe is that London is one of the greatest cities on this planet. But really London is a series of quite different 'villages' with many different flavours and positives. Some areas are simply awful (and to be avoided) but generally speaking once out of the inner areas (too busy, too much traffic) London can be a great place to live in with lots of open spaces, nice people and a settled feel. But yeah, far too expensive - particularly housing.
