Yes, language changes. But it doesn't allow eBook or pBook, despite what how some market-droids use it. The way language changes is to drop hyphens, "to-day" became "today", thus e-mail becomes email and e-book becomes ebook.
The language never allows capitals in anything but a proper noun or in acronyms, it is inevitable that any attempts by market-droids to use eBook will fail, and ebook will become the standard. There's simply no reason for the capital B, and without that reason, it is certain to fade out. It's doubly certain with capitalizing the second letter of a word, this only works as the proper name of a specific product. iPod would quickly become ipod if it was a generic term instead of a specific product.
