Hardly any academics, or professionals who write articles, reports, or serious documents, are doing so exclusively on their iPad. They probably own an iPad, but the majority of people I see who are trying to contribute something substantial to the world - a book, design, quality video and sound recording, or just professional documents to share with colleagues... these people are using a laptop or a desktop. Their PC might be old, but it does the job. These people own tablets and phones too. Now do the math. If everyone - smart, average, stupid, young, old, are buying tablets and smartphones, then of course this makes PC sales look like death. It's more like a "post-PC-avoidance" world we're in now. A lot of stupid people avoided using PCs back in the day. Now all those people own tablets and smartphones and use them for entertainment.
