I still have a landline here, but only because it's a package deal with our Internet service. The good thing is that if it rings, I know it's the wrong number or a BS sales call. I only use it to order food.
As for cell phones, I hate 'em but I need 'em. I don't get many social calls, just work stuff. Also it makes my email life a cinch. Just like text messaging. I hate myself for needing one.
