Not that I really want to extend this thread any more...But I have had both DSL and Cable, and I like DSL better. I had Time Warner's Cablemodem (running on Roadrunner's fiber). Installation time was decent, and it was pretty fast, but not as fast as DSL, especially during "peak times" (when you're home from work or school, and everyone and their brother is on-line).
Cable is run into a neighborhood, and imagine a water pipe. If you're the only one drawing water from the water pipe, you've got great pressure. But if all of your neighbors are also drawing water from that same pipe at the same time, your pressure sucks. That's how cable works.
I got DSL about 2 months ago here (they finally offered it in my area), and I love it. They overnighted me the hardware, had an easy self-installation setup, and turned on my service about a week before they promised to. Speeds are excellent, and my service has only gone out once, for a 2-hour period of time one morning. And it's slightly cheaper than cable, compared to both of my experiences.
Another plus is that I already had a phone jack wired into my office, but not a cable jack.
