@nick_rampart: Investment = Productivity
A popular mantra that does not always work depending on the precise circumstances.
"Productivity" is a perfectly valid concept for business users, but it hardly applies to domestic / residential systems. A business may invest with the intention of improving productivity as a result of that investment; all well and good. A business may want someone else to invest in the hope of achieving productivity gains as a result; if its costs of doing business increase as a result then it pays for those increases from the income it obtains from its customers.
However, the way things are going, or are likely to go, with broadband, the fibre - fetishists who cannot and will not differentiate between business and non - business users are handing BT a perfect excuse to increase everyones' costs by force - feeding full fibre broadband (costs) to all users, whether they need it or not.
If business wants it, let business pay for it. Don't force domestic users into the same model on the grounds of "productivity".
