Last week Amazon announced the launch of the Kindle DX in the USA and it will soon find its way to the UK. The new version of this electronic book reader appears to be slim, lightweight and holds 3500 books. As a gadget lover and an avid book reader, my first reaction to this is: 'fantastic  - just what I need'. My wife agrees on the basis it might stop me leaving the half-a-dozen or so books I’m reading at any one time around the house. One of the primary markets for the Kindle DX is said to be the university sector and immediately you can see the benefit for students of having all their books easily to hand with the ability to cross reference quickly. Indeed a university could download your reading list to you when you sign up, with relevant key chapters perhaps highlighted. The readability of the text is excellent and with a long battery life, the slim, easy to hold Kindle DX (have you seen the size of some text books?) could work well for students. In the corporate world, I’m not sure how it would replace all the books that executives like to leave lying around the office or stacked in their bookcase, but I could see it being a useful tool for providing a lot of text for studying, particularly when travelling. It might also be a good way of supplying diagrams and instructional text to engineers and knowledge workers with limited online access. So, depending on the performance need, it may have a use. However, the cost of US$489 at launch seems to be very steep, and outside most student's budget. Also, as a way of taking a stack of books on holiday, it becomes another expensive gadget to watch over. So for my summer holidays this year it won’t be a Kindle DX, but a load of paperbacks, that if I lose I won’t mind and from which I’ll still get that wonderful tactile thrill of opening and holding a new book.
