There is a certain inevitability that ebook sales have now overtaken paperback sales on Amazon’s US site.Amazon’s

Kindle 2 is so light and so cheap that it’s easy to see why people have rushed to buy it.Though I’m still not keen on the design of the Kindle,it is a vast improvement on its predecessor and certainly tolerable.Beyond the device itself,Amazon has done a great job of rolling out Kindle apps,ensuring that people like me-who have an iPad but not a Kindle can still join in the fun.

Once you’re into the Kindle ecosystem,Amazon locks you in tightly-just as Apple does with its iTunes/iPod ecosystem.It’s so easy to buy from Amazon’s store and the books are so cheap that it’s not worth the effort of going elsewhere.

e-books with printed ones-in much the same way that film studio DVDs with digital copies of films.There’s no reason to think

that lovers of printed books will change their minds.There will undoubtedly be fewer of them as time goes by because more

people will grow up with ebooks an
