<P><FONT SIZE=2>There is no argument that fibre is a superior technology, but at what cost? Consumers make no definition between the way in which a service is delivered - they care only about the performance of the product. The proliferation of 3G services is a testament to this.<BR>

Process vs Product. Product sells, process does not.<BR>

I still consider fibre a far better alternative in terms of upgrades for<BR>
our future development rather than the age-old degrading copper<BR>
infrastructure.<BR>
