wow, there's so much wrong with this...
... I don't know where to begin.
Tablets are *not* the wave of the future. They are the wave of a future for a particular group of people -- the content consumers. One could even stipulate that most PC users are content consumers the great majority of the time.
But to have content to consume, you need content creators. Other than taking a low quality photo and drawing a moustache on it, tablets suck at content creation. There will still be a need for PCs. I'll be happy to revisit this when Adobe produces a usable touch-only version of their Creative Suite. (I know, they're working on this for some pieces of the suite, but they're not working very hard, partly because of the perception -- warranted -- that content creators do not use tablets.)
And this brings us to Windows 8. It's a little screwy but somewhat usable on a touch-only device, (although for some things you will still have to attach the optional keyboard) but on a desktop machine, the machine on which content is created, it's pants. I'm sure Microsoft knows this; they're not idiots. But they pushed on anyway, no doubt thinking that they'll make enough on the Surface to balance the losses they'll experience in the desktop model.
"Intuitive?" Are we talking about the same Windows 8? Ok, you have never seen Win8 before. I hand you a slab. You can scrape your finger across the screen, see some squares which don't always tell you exactly what they are. Some have dynamic content. You touch one, and an app opens up. Ok, now I want to do something else. HOW DO YOU DISMISS THE APP? There's nothing obvious to press -- no conveyance -- to tell you what to do next. How do you get to the control panel? How do you turn the damned thing off? All of these questions have answers, but you have to learn them elsewhere, or divine them by random scraping similar to finding easter eggs in a first person shooter.
iOS? Intuitive, yes, if somewhat limited and boring. Android? Intuitive enough that my 73 year old mother can pick one up and make it do stuff. But Windows 8? It should be renamed WTF, because that's the phrase you'll be repeating over and over.
Moore's Law didn't need to continue indefinitely, it only needed to continue until PCs are Good Enough. And now they are. There are still performance bumps possible -- denser memory, faster disk (mechanical or solid state), better caching algorithms, but commodity computers are Fast Enough for most people right now. Computers that are not upgradable seem wasteful to me, but it is what it is. If the computer starts out Fast Enough, and is cheap enough, I'm happy with replacing it when my requirements change.
From Task Manager, I list 18 apps currently running, 40 processes and close to 60 services. The CPU Usage tab shows all these disparate programs running roughly evenly across all four cores. Even with only 1 app running, I still have a pantload of processes and services, more or less evenly distributed across the cores.
So no, unless you're running Lotus 123 from a Dos prompt, you can't help but have many many things churning around just under the surface, even if you don't realize that this is the case. "If you run just one app you need only one core" is an idiotic statement for anyone who professes to write for a technical website. Multiple cores really do buy you a lot in an OS with proper multitasking. It's almost as if the author is making a case for single tasking because Metro tends to run apps full screen -- getting us used to the idea that no, we really didn't want to do more than one thing at a time. It just doesn't fly.
There's a LOT more wrong with the article, but I'm out of time and need to get back to work. In summary, the entire article tries to wrap up some idiotic conclusions in a few half-truths and some outrageous ... well, let's call them Misunderstandings. We aren't going to an all-tablet world anytime soon. Windows 8 continues to be Pants, and was probably Ballmer's worst mistake in a long series of arrogant blunders.
