hi,
i definately was agreeing as below but it appears for the most
part the cable co are advertising their 'fast' connections myths
better than the telephony co are selling their xDLS connections.
hopefully the better of the two technology will rise to the occasion.
but then again we all know the debate between beta and vhs formats.
unix versus m$ and so on. perhaps if we all demand xDSL from all
parties then we will see the evolution of xDSL as a standard for
connectivity to the I.
