There are lots of opinions of the best programs to use to get your family history data on to the computer, etc. One I ran across today from one of my RSS feeds is from Gizmo, a site which reviews FREE software in general.
The posting today lists some of the most popular FREE genealogy programs. For most of us (and especially for those just starting to get your data on your computer) these programs will work just as well as the ones you have to buy. It would be possible to start here and never use any other program, or a person could start here and upgrade to a commercial program later.
