Do you know how many millions of iPods are out there? Deutsche Bank says that by the end of the year, 31 million units will be sold. What's even more interesting is that the users' appetite for Apple's well-known player won't be any different next year, Deutsche Bank estimating that in 2006, the Cupertino company will sell 43 million iPods. If the figures are confirmed, we cannot help but wonder where will iPod's market share stop, the player already owning 75% of the MP3 player market.

In any case, iPod nano will be one of the engines that ensure Apple the ascension to online music download domination. In fact, Deutsche Bank's report confirms that Apple is the company that gets the most out of digital music. The report also mentions that Apple would be the perfect company to become a distributor of video content.
