Advantage: VoIP
My parents are scheduled to close on their new house a week from today! One major hassle about moving is telling everyone your new phone number. Enter Vonage. Most VoIP providers allow you to transfer your old land-line number over to VoIP. When you move, simply take your VoIP modem with you and the number stays with it! I did the same thing when I moved from my apartment to my condo. After messing around with the Linksys router a bit, the actual setup process took no time at all. On top of the convenience of keeping the same number, their monthly phone bill goes from over $100 per month to around $25 per month.
