I took the plunge today and signed up for AT&T's DSL service. It was pretty much a done-deal after we moved from Comcast to Dish Network late last year, since we lost the discount we got by having bundled internet and TV service. Our cable modem internet service now costs us $60/month. That is too much to continue paying, even though I am quite happy with their support.
It was 9 years ago when I signed-up for Time-Warner's RoadRunner cable modem service. I was among the first in my area to get it. I recall that the first year or so of the service, we had outages fairly often - maybe once a week. But the last 6-7 years have been very reliable - maybe one outage event a year.
I've been a little weary of DSL because of the speed (it seems it's not as fast as a cable modem), but I signed up for the lite level, which claims up to 6Mbps download speeds (I'm going to check my current speed with RoadRunner at http://www.speakeasy.net/speedtest/ and see how that compares to my DSL service). And at $35/month plus a $100 rebate for switching from Comcast, the activation energy for making the switch has been reached.
A nice perk is that the modem they'll send is part of a wireless router, so I should be able to connect my Wii up to the network. I have an aging Airport base station, but it stopped working a few years ago, and I haven't spent the time troubleshooting to determine if it is fixable or not.
I'll let you know if my move to DSL is as smooth as I hope it will be.
