This month's Fast Company features a cover story about Amazon's Kindle. It describes how Amazon could use the Kindle to squeeze publishers out of the book value chain. It also talks about how Apple might respond, and what the ensuing battle might look like.
Over the past few years I've been impressed by Amazon's willingness to create products and services in markets where there still is really no business - like Kindle. They constantly look for opportunities to leverage their distribution, retail expertise, and infrastructure to grow their business and increase their relevance to consumers and merchants. On the other hand, ebay stuck to its knitting, failed to grow out of the U.S. auctions business, and had its lunch eaten by craigslist.
