Query: Dud

According to many of the reviews on Amazon this is a great machine. However, that has not been my experience. To start off, the instructions are at best wholly inadequate - making it difficult to get started (and I am relatively good at computer gadgets). Second, the unit stopped working (just froze into an expensive paperweight) after about 10 minutes of use. I am going to return this unit and exchange it for another one. Maybe I just got the exceptional dud, but maybe I didn't.
