Interested in your post, Mondano, because I am an author, and am curious to hear the opinions of someone in the other end of the publishing industry.
I am going to buy one of these for a whole raft of reasons. First of all, whether we like it or not, e-publishing is about to go mainstream, and I see more point in exploring it with something like an Ipad that I know will work beautifully with my work computers than something like a Kindle or Sony E-reader that only does one thing. From a practical point of view, I can see myself taking it around the house with me, reading and editing my manuscripts, sitting up in bed to work (oh, so much easier than a laptop), throwing it in my handbag when I am out and about, taking it with me on business trips. (I am a great devotee of the hardcover book, but oh, the bliss of being able to carry seven or eight books with me onto a plane without adding kilos to my luggage allowance.)
I have never had the slightest desire to own an iPhone or an iPod touch. I have a perfectly good iPod for my music, and I have a phone that works just fine for when I want to make calls or snap off a photo. The screen on those things is just too fiddly for anything else, but the iPad I can really see as being truly useful. I could not care less about Flash, or the MacOSX not being included. As long as it will run Pages and Numbers, play movies when I am travelling, allow me to read documents, get my email and show a few pictures, I will be happy; and I know it will do all those things and a heap more beside I haven't even thought of.
My first Apple computer was a II+ in about 1980. I've been using them for my work ever since and am more excited about this than anything else they have ever introduced.
