The iPad is a hit already, a product that is just only announced, but won’t be available in about 60 more days is causing a revolution of good, bad and speculative reviews and consideration from all sides and one side that is more than suffering with the recent announcement is Amazon.com, in direct competition with the newly iBookStore that has been fighting MacMillan’s intentions to hike the ebook prices to the iPad level.

But just when We saw a banning on all MacMillan’s books from Amazon.com and then a reconsideration from Amazon to MacMillan request, now is HarperCollins who is trying to take advantage of Amazon and MacMillan agreement with a new price adjustment for HarperCollins’ own books.

So, maybe the iPad is not available now, but you can see the tsunami is causing in the whole industry.
