As a rookie family historian, I started with FTM 2005 and loved it. It was easy to use - being a woman any 'help' file is always a last, rather than first, resort! - and I never needed to use it. I never did quite work out how to publish a 'Book', but since it wasn't something I wanted or needed to do, it suited me fine. I thought the charts were a bit limited, but again being a rookie I was content enough.
Had I not lost the installation disk over the years I'd still be using it on my new computer. However, if anyone asks my advice on upgrading I'd have to say keep well away from FTM 2008 - in fact I have a boxed copy, installed once and un-installed within 24 hours - which anyone can have for the cost of the postage.
