Okay, so my iPad 2 is on the way, and it's really my first experience with an Apple product other than my ipod. I'm a writer, and I'm hoping to use my iPad 2 to do some writing alongside all of the other fun. Is the touch screen keyboard good for writing? If not, is there a recommended keyboard? I saw that new Zagg keyboard case, but I couldn't get a good look at the keyboard layout from the images on amazon. Also, the keyboard is bluetooth. Does that mean that it uses batteries that you have to replace and/or charge separately from the iPad 2? And, last question (I promise!), is there some professional quality writing software for iPad that can save in .doc format? Like a Word clone or something? Thanks!
