I've been thinking about the rationale behind the Kindle DX. Why would Amazon want to release something so large and expensive? You could purchase a mobile computer (like a laptop or netbook) for the same amount. Does it really make sense to release an e-book reader that's so expensive?
The folks over at Amazon must really think that people are willing to replace textbooks with e-books. I'm a big fan of being paperless, but that's why I use my convertible Lenovo Thinkpad X200 tablet PC. I have a large color screen (12") and I can read all the PDFs I want to without panning, scrolling, etc.
How will the Apple iPad (I call it that right now, but it could end up being called the MacPad, MacTablet or iTablet) change the way people view these portable digital devices? Many people read on their iPhone. Will a larger tablet-sized gadget be preferred? How will doctors react to this surge of slate tablet-type gadgets? Will physicians become more inclined to embrace pen-based input and move away from the keyboard? Will Microsoft Surface reinforce the fact that you can be so much more efficient if you're using natural touch and finger gestures?
