I doubt I'll ever get VOIP. During a recent power outage it was clear that having television and internet services from the same company was just not a good idea. And although, I am strictly cell phone now, I don't see any reason to get VOIP.
If for some reason I do it won't be from the same company I get my internet service from. I just don't want to have to rely on one company to get information during an emergency.
