You certainly are in front of the crowd!

But since you have asked….

I like the cover, the title, and think you should go with just the pdf - I never bought a book when I can download it.

Oh , and on the scale of 1 - 10. I am sure your book rocks and the content is fantastic but since I already have 1,00,000 ebooks on traffic, making money online, and everything else under the sun I will hold out until your super powerful copy on the sales page whips me into a super excited state convincing me your book is better than all the rest to rate my excitment level.

What is the purpose of the book? Is it a lead generator? If so, the Dan Kennedy No B.S. books might be helpful to look at. They are great books by themselves but they also have many other offers & upsells.

This is definitely a topic of interest but how can I get “10″ excited over a book….maybe if you’re putting centerfolds in it. What is the release date?

If you sell it as a download what difference does the cover make—unless you print it off. In which case I would imagine the printing machine will flashback on an old LSD trip.
You decide if thats good or bad. hahhahahahahahahahahahaahaha

my preference is for a download version,as i live in Czech Republic and getting books shipped here is a pain seen as half the post from the U.S. goes “missing”. But here’s is an idea!, Why not allow people download the book after they have ordered the print version?
