My bias is that most people should focus more on taking good photographs - paying attention to lighting, exposure, composition, etc. - than on technology. It takes a lot of editing to fix a bad shot. So the fact that this is written by a photographer is another big plus (though he appears to do mostly coffee table books, rather than guides).

A better book for some is Steve Bavister's Digital Photography. It's much clearer on the key fundamentals of photography. It has less detail all around, but that is a plus for those who want the main ideas quickly or looking for an accessible introduction. That's the book I bought for my teenage nephew; he's smart, but given his limited experience, I thought it better to give him a book with more emphasis on photography.

Note that Freeman's book discusses technical aspects of hardware and software generically, not specific to any program, which may be a negative for those users looking for a step-by-step guide to their programs or software. Also, if you don't think you'll ever do more than resize or fix red-eye, the technical discussion may not be much use to you. OR, it may open your eyes to what can be done!

Another set of alternatives, for a narrower group of users looking more for specifics on the technical aspects of hardware and software, are books like Long's Complete Digital Photography. But those books don't use photos and illustrations in the text, and are written by technical writers - not photographers. They emphasize the "digital" far more than the "photography," and aren't good as an all-in-one first book.
