I have no landline, but I do have cellphone. However, it's furnished by my company so.... No phone bills either!
If I ever need a phone though, I'm tempted to try out Vonage since I really don't want to give up my broadband, or perhaps a pre-pay if I want to stick to a cellphone.
Internet access is the only non-essential expense that I pay right now, and that's currently $40 per month.
