Do they finally allow 911 calls with VOIP? I'd be worred about that. I guess cell phones can be used though. There's also the issue of power cuts. I seem to have them often in my area so I'd lose the phone during those times. You may also have the odd time that your internet cannot connect because of services or or anything else so you may lose your phone then too. Basically it's great if you want to have a LOT of features on your phoneline but for some people who just want either nothing or maybe call waiting, the price difference is almost nothing.
