does FaceTime only work with another mac?
FaceTime only works with the iPad, iPhone or iPod touch with iOS 5 or newer and Macs with Mac OS X Snow Leopard or newer
See answer on FaceTime from mende1.
I much prefer Skype as it works cross-platform. Windows, OS X and IOS are all supported
I use Skype on my iPad/iPhone to 'talk' to relatives around the world who are mainly Windows users.
