Why am I interested in the iPad?
To a degree, the iPad is going to change how people interact with computers. I don't think we will see a complete elimination of the keyboard and mouse. But I do think we're going to see a gradual shift toward touch, gesture, etc. Maybe eventually, computers and other devices will become more and more "invisible" so to speak.
Reading, watching movies, surfing the Internet.
My main gadget is a Macbook. I also have an iPhone. I love both Apple products. From time to time I use my wife's Windows machine with (ugh) the Vista operating system.
