That seems to me to be begging the question. I see no evidence that the desktop will "die out". It may change form, and it may be used by a smaller percentage

That seems to me to be begging the question. I see no evidence that the desktop will "die out". It may change form, and it may be used by a smaller percentage of the computing public, but the idea that we're going to see a time without significant usage of desktop (or laptop) computers within the foreseeable future just seems laughable to me. It smacks, to me, of the idea that the only thing worth being in the market is the very top: the company selling the biggest product, making the most money—otherwise you might as well not even bother. This is toxic thinking.
