It is kind of ironic that books, which can be digitalized much easier than sound or video, are the last medium that resists against being swept away by the digital revolution. The reason may be that the traditional book is a pretty good mobile device already and as opposed to music or video, where one wants to spontaneously select a song or movie, it's easy to choose a book that lasts for the day, when you are on the road.
This may change with Amazon's Kindle. As opposed to previous attempts to establish eBook reading on the mass market, I think this one has the chance to really transform how we read. For two reasons: first, it's from Amazon, which is already the primary site for many readers to buy books. Second, because of the excellent idea to deliver content wirelessly, without a monthly contract, but also without installing software, syncing and without adding more cables to the clutter at the desk.
Here is how it works: You go to Amazon.com and select a title that is available in Kindle format. Most likely, faster than you can go to the content page on the Kindle, the title will be downloaded and is ready for reading. Also nice: you can first download some pages for free, before you purchase the full book. A slightly stripped down version of the Amazon bookstore is also available on the Kindle directly, so in theory you could use it even completely without owning a PC.
The design and usability is functional, but the device doesn't feel nearly as good as, for example, anything built by Apple. There's a next page button on each side, so you can comfortably use it with either hand. For some reason, however, the Kindle is asymmetric, with a bias to hold it with your right hand. The readability of the display is great - the eInk technology allows reading even in bright sunshine. On the other hand, in the dark, the Kindle is as useless as a paper book and there's no built-in light. Also eInk is much slower than a LCD display, so while you can write a full review directly on the Kindle, it's probably not really fun. In order to get around this, the Kindle has a select bar outside of the main display, which is used to select menus and lines in the text for marking up or adding notes. A great feature is the built-in dictionary, which is somewhat slow, but still much faster than looking up a word in a real dictionary.
So what's not to like? First, of course, the copy-protected content. I wouldn't mind so much, because I don't really read books multiple times, but it also prevents sharing books with friends and family, which is part of the fun you can have with books. I can't imagine that publishers and Amazon believe that they can make friends and family pay the full price for a book that they just could have borrowed. So they have to come up with some way of sharing content and the fact that the content files are not easily available open up interesting possibilities.
The display is great, but there's room for improvement. The background is not really paper white, rather grayish, and of course we really want to have color. But all this is probably only a matter of time as the eInk technology evolves.
Lastly, 90,000 Kindle books sounds like a lot to choose from, but if you're looking for a specific book, chances are pretty high that it's not available for the Kindle. The device is currently sold out, so there's a real possibility that it reaches a critical mass that forces all publishers to provide a Kindle edition. If not, the Kindle will remain not much more than an interesting gadget.
