Too many times, a company will develop a “next generation” product and stop selling the old one. They expect their customers to evolve, failing to realize that not all customers want to change. They like things the way they were, and they get upset when you take it away.

You hit it bang on the head (the nail), with those words. I personally think that Kindle is a revolution. Of course, with so many critics betting against it, Amazon now has the ability to put a little bit more thought before the next version of this!

I also wanted to point out the significance of your words from the software industry. With the advent of the next gen OSs from Microsoft and Apple, there is a lot of flak from the customer base that they have gone way ahead with revolutionizing the interface, so much so that it’s at a cost of usability. Worse, there’s no way to exchange the “innovation” for “tradition”.

Good point!
