Over the past couple years, i've had maybe 3 outages w/ our Cable (internet only) that lasted 10mins or so.
IMHO, the Cable vs DSL debate is a matter of location and carrier, not the service itself.
Basically, I only watch TV because I have a Tivo. (Tivo Brand Tivo).
I've got certain shows I record daily, maybe watch 3 episodes of each per week.
We pay ~$145/mo to the Cable Company for the TV, phone, and internet + another $20ish to Sprint for unlimited long distance.
Out of 900 some odd channels, I only watch maybe a dozen.
