Yet another sad example of "people who like tech that I don't like are wrong!"
People have different requirements and preferences. For many people who don't touch type, full size keyboards are not as easy to use as you might think. Personally, every time I type more than one paragraph on my iPad's horrible (some people like it though) onscreen keyboard, I want to scream. And yearn for a nice stylus and handwriting recognition. Like my old HP Vista tablet edition thingamijig with the fold-away keyboard. Others think that is pants, which is why the iPad didn't have one until very recently, and even now have deliberately crippled it to make it a drawing tool that you have to bodge to get it to do handwriting.
