Donny, Again, I think you're misunderstanding my comments. Instead of retyping my thoughts I will post a 'post' and link to the 'post' - (from Motley Fool), which clearly articulates what I intended to..... COPIED FROM MOTLEY FOOL: boards.fool.com "The problem is usually not inthe local loop as much as in the upstream pipe. Cable and DSL use two different ways of handling the local loop. One puts quite a few people on a high speed trunk while the other gives a medium to low speed trunk to each person. If this were the only consideration, then cable would give you a higher burst rate but DSL would give you a higher sustainable rate. The problem comes in when you get off of the local loop. Once your cable data gets to the cable company's head end room, it is put into an upstream pipe. This pipe may be a bit smaller than the cable pipe (for a reason discussed below), or multiple cable trunks may aggregate into one upstream pipe. For DSL, the indivudal house pipes are all dumped into one (or multiple) higher speed upstream pipe. This upstream pipe is not going to be the same size as all the household pipes combined. As you can see, in either case, if a lot of people get on the system, it is possible to saturate the upstream pipe and drag down everyone's performance. It doesn't matter how much bandwidth comes into your house if a 1000 houses share a single upstream trunk. As mentioned above, even in cable modem systems there might be a place where the upstream pipe doesn't match the local loop bandwidth. This is likely because multiple channels over the cable are being aggregated into one pipe and an asusmption is being made that not all the pipes will be full at the same time. Also, some relief can be found by putting proxy servers at these headend points to cache the common data such as the Yahoo home page or the graphics at Excite's home page. What is really comes down to is that neither system is fundamentally better than the other. Distance limitations may preclude some people from getting DSL. Lack of head-end points may limit the bandwidth for some people with cable modems. It all comes down to what is available in your area and how much you are willing to pay. I'd be happy to have either service right now. Both are within a few miles of me, but neither is in my neighborhood. Oh well."
