Ric - as an example - an ebook seller's policy is that you choose the format in which you make your purchase:
Options:
DE
Mobi Reader
Microsoft Reader
If a customer has (in the past) purchased (and is familiar with .pdf files) using Adobe Reader and that customer sees the bookseller reference .pdf when DE is mentioned, that customer (namely me in this instance) automatically assumes that the .pdf version is the one that is easier to deal with and will allow that customer to "read" that book on almost any device that they own (i. e. - work laptop, home computer, blackberry phone, PDA), that customer excitedly buys that book by selecting DE (dumb customer not realizing DE is NOT the same as Reader 7).
Ta Da - customer discovers - oops I can't open this file on my PDA. Oops, I can't open this file on my blackberry. What can I do?
Bookseller won't reload your purchase in a new format (Mobi Reader)so you can read your book on your blackberry at the doctor's office, at the airport, in your hotel room while you are traveling.
You can always download (again)the book from that bookseller , but it stays in that original format. Adobe Reader 7 is NOT an option with this bookseller.
I bought a series of books in April 2007 using DE. Big mistake on my part. I have not started reading my books because I couldn't get them on my blackberry.
Fortunately, I have resolved my problem. Everyone is not so lucky.
Anyway - my ultimate point in my messages is that Adobe has been a huge let down as it relates to DE, that's all.
Good Luck with making improvements. I am now officially a Mobi Reader customer.
