Beagle,
That is an interesting opinion regarding the iPad, but doesn't fit my experience. Looking over the lists further up, you find numerous utilities for iPads and iPhones that increase productivity many times over. All the world's approach plates at your fingertips on the iPad, various calculators, great battery life, the e-mail interface is fantastic, especially if you have several accounts...they ALL come up, without having to use a browser!
I do have a couple entertainment Apps, but for the most part it is work-related and the built in screen keyboard, shifts for me from Nordic, German and English keyboards with a single tap. Absolutely brilliant and I find that I need the "real computer," only about 15% of the time. In addition, I now also have a library of books with me in iBooks, can convert PDFs to "books" and have vast amounts of useful reference materials in a searchable format in a smallish shoulder bag.
But heh.....there is a charm to pen and paper, vintage motorcycles and antiques, so use what works and makes your day.
