Hi Jim,
Marty got in before me and answered your question.
Yes, I use Adobe Acrobat PDF for my ebook.
(I hope you were able to read my ebook from the link and password I sent you)
Acrobat also has these advantages;
1. Cross platform - both Mac & PC - can be viewed by any type of computer that has the free Adobe Reader installed.
2. Over 100,000,000 users world wide - Industry standard
3. PDF ebooks & documents will be able to be read on Microsoft's "ebook Reader" which will no doubt be included with future versions of Windows as standard.
4. Built in Security features - password protection
5. Convert to PDF from any word processor / desktop publishing software with ease.
6. Good compression - smaller file sizes, leading to faster downloads
7. Reliability- I've never had a customer who could not open and read my ebook in PDF.
Hope this helps
Ricky
