I love it: now when I buy a Kindle book from Amazon.com, I can have it on my iPhone, my iPad, my Mac laptop, my Windows laptop, my Mac Desktop, or my Windows desktop.
This makes me feel like I really own the book. If I have a spare 10 minutes, just about wherever I am, I can read the book. It’s great usability. Great convenience.
And I love the business strategy implications. By making Kindle books available on every possible hardware device, Amazon chooses not to reserve them for people who buy the Kindle hardware. Is this a sacrifice? Helping competitors? Does the iPad make the Kindle less desireable? Yes? Does having Kindle books available on the iPad mean Amazon.com will sell more Kindle books? Yes.
On the long term, Amazon wins because it focuses on what it does really well. Kindle books become the standard. It’s called focus. And strategy is focus.
