With a simple photograph I’ll try to illustrate why the Apple iPad, in my mind, is an essential travel device. Between iBooks, amazon.com, and borders.com there are no shortage of travel guides available to the eBook market. Also, with Zinio, you can manage your magazine subscriptions so they are delivered as digital subscriptions every month (save a tree). With many airlines charging for each piece of luggage and every kilo over a certain limit, it makes more and more sense to put one of these babies in your carry-on. I don’t leave home without it!
