Amazon, iPad and other rants and ravings

I came across a story on the Internet which sheds some light, I believe, on the future of ebooks with regard to Amazon and Apple.

I think this is interesting and the info could be a money saver since I have noticed there are sites that are offering - at a charge, of course, ways to format your books to be purchased and read on an iPad.
To me, there are thousands of sites offering ways for you to sell books by using their marketing services. Naturally, for a price.
I am amazed by the amounts being charged for these services, some nearly $5,000!
I know marketing is important but at what price. How many books need to be sold just to break even and none of these services can promise you will break even.
I am giving serious thought to switching from Lulu to CreateSpace for two or three simple reasons.
One, CreateSpace is Amazon and I will bet most books sold on the Internet are sold through Amazon.
Two, I can lower the retail, wholesale and to me cost of my books.
Three, When it comes to ebooks, there again it looks like Amazon will continue to dominate,
One other plan in the works is to consolidate my two vampire novels into one new novel that will also include the third vampire book I am now writing.
I do have an agent and friend who thinks this is a good idea. She thinks we have a good chance at finding a traditional publisher. And, she loves the title: And God Created Vampires.
Thanks for your time. I hope you found this interesting.
