I usually love Peter's articles, but the thing that stood out to me in this review is his instance on spending a whole page complaining that the desktop buttons were too hard to hit with a touchscreen. This is why I say he doesn't seem to know the difference. Windows 8, especially the desktop, begs for a mouse and keyboard. Windows 8 desktop is essentially Windows 7, which wasn't good with touch either.
By complaining that it's bad for touch, he's asking Microsoft to make it better for touch. They did! It's called Windows RT. Windows RT is the Windows desktop but designed for touch. It's like complaining that Apple doesn't make a phone based off Mac software but designed for a small form factor and with a touch screen. They do! You're just looking for it in the wrong place.
