FaceTime without an iPhone
Is it possible to use FaceTime without having an iPhone? More in particular; is it possible to use FaceTime only having an iPad?
I currently live abroad and video call quality of other providers is terrible, so I am considering buying and shipping to my family an iPad so I can call them over a higher quality and more reliable service. (Among other things, like they will like such a gadget!)
Is this possible? Should I simply ship an iPhone instead?
