If yer not a bumpkin or something, cellphones are the way to go. For me, it's 40$ a month for a phone line, and any amount per month (+10$ service..wtf?). I don't use the cellphone for extended periods of time (I try to keep calls < 1 minute) for a cellphone (I drop 10-20$), so it works in my favour.
