Rather reviewing Samsung's S8000 from the Press release, I've actually been putting the handset through its paces. Some interesting discoveries have resulted – including the fact that the GPS facility appears to be disabled in the UK version. The first thing that strikes you is the user interface. Given that I'm no great fan of the iPhone, the fact that the S8000 looks similar doesn't help. Anyone who assumes that a touch screen interface is always user-friendly would be seriously wrong. In the S8000's case, the UI can be described as powerful and complex but certainly not friendly. It's a long time since a handset has sent me scurrying for its quick guide and then had me printing out the user manual. Why? Because, in the S8000 - aka the Jet - 's case, in addition to tapping on the screen, you also need to learn what functions at least four other buttons perform.
