Well I use it often with my lady friend, daughter and grand kids.
You need a relatively new and fast computer, a fast internet connection, and a webcam & microphone.
Most computers built in the last few years will do the job and especially laptops & notebooks.
I also have a KIndle Fire HD that I can skype from and it is very handy.
Video calls in the US, Canada & Mexico are free but international calls come at a price which is very reasonable.
If you are computer literate it is very easy to set up, however, be very careful and read all popup windows carefully before you click.
I am by no means an expert on Skype so download it, read everything carefully and try it out.
