I'm on the MagicJack now! I really like it. I was paying 100 a month for my cell phone then decided to ditch that and get DSL and a MagicJack. paying 40 a month for the Internet, but splitting that with my roommate. so its more like 20 a month for the internet, and the Magic Jack is paid up. I'm saving an extra $80 a month. its pretty fantastic.
Thanks to iwrock I have a junky old Compaq running in my closet, so the phone is on all the time, and I never worry about it going out when i turn off my computer. that coupled via the MagicJack to one of those 3 phone cordless phone setups I have phone through out my house.
Here is my phone closet!
