I bought Magic Jack and it can be used on any computer. I have one major complaint and because of it no longer use it. My complaint is that when the phone rings a screen pops up on your computer and if you are typing at that time it keeps you from typing anything else until you delete that screen. It was a pain since I do school online and have timed test. I would just unplug the phone when I needed to not be interrupted, but it became a big hassle.
