Slimboli,
I don't know about outdated, I have never heard that. As far as I knew, cable modems where the newer technology!! Yes, I heard about sharing and the more people on the same grid, the slower the speeds. But I have had it for over a year and a half and it's just as fast as it ever was! .....and I live in LI, NY where there are plenty of people to tie up the grid!!
I had DSL and the speed can't compare. For example, downloading MP3's on Kazza with DSL I averaged 65-70 kbs. With the cable modem I average 210-235 kbs. That's a BIG difference! Also, like Cwilhelmi said, it's cheaper. I was paying $49.95 per month with Verizon DSL (local phone co.) With Cablevision, I'm paying $29.95 a month.
DSL is very good. Like I said, I had it for 2 years because cable wasn't available in my area, but when it was, I switched and I love it.
You won't go wrong with Pacbell and as far as going out of business, that's one worry you won't have. Good luck with it, heres wishing you great speeds and fast downloads!!
Joe
