Evanelpus,
Quit the Apple bashing. You quite obviously have no evidence to support your vast claims beyond your limited personal experience, which was further limited by what some man from Tesco told you.
There are millions of happy Facetime users out there, millions of happy Apple product users out there. As with most things in the world of IT (Apple or otherwise) there will always be edge-cases that are more difficult to fix.
Assuming your problem is an actual problem, then you may just be an edge case. Otherwise, as others have said, you may just have missed someting in your setup.
