Joe Konrath has said that he sells 60 eBooks on Kindle for every 1 he sells as an iBook. This is in contrast to Steve Job’s claim that Apple has 22% of the market. Here is the full quote from The Next Web-
“Publishers might be looking at enriched or enhanced ebooks as their new big-ticket items to replace hardcovers. But the major ebook retailer, Amazon, isn’t set up for video. Kindle isn’t even able to do color yet. That leaves Apple, and according to my numbers Apple is a very small part of the ebook market. I sell 200 ebooks a day on Kindle. On iPad, I sell 100 a month.”
Not surprising given that Kindle is multi platform and I found greater variety at Amazon. Also about prices, but iBook books do seem expensive in £s.
Some iBooks are cheaper than on Kindle but very few. I always shop around.
I buy my ebooks via Amazon but read them on my iPad and iPhone.
