re: Windows 8 Won't Be Saved By Keyboards
IMO -- the key issue with Microsoft's new UI is they expected folks to learn it by trial and error. Most times it isn't at all obvious what you are supposed to do next. iOS apps are considerably more intuitive than Windows 8 (both the OS itself and its built-in apps). I have not tried the update (8.1) but if it still expects folks to guess what to do next, expect the general public to reject it.
The most vivid example is when, by default, a desktop browser window wants to view a PDF. In Windows 7 the browser would typically open the document inside the browser or, at worst, open a separate window that hovers over the original page or appears in a different browser tab. When finished, returning to the prior page is ridiculously obvious. In Windows 8, all continuity is lost as the user stares at the modern viewer that doesn't offer them any clues as to how to get back to the prior page. Of course after one LEARNS what to do (a left to right swipe into the screen and then tap on the desktop task), it's rather simple to return but what was Microsoft smoking when it decided this was a good thing?
In fairness, my iPhone has similar challenges. For instance, when I am in the stock market app, headlines open in Safari and I have to double-tap the button to bring up the task list and return to the app when I'm finished. However, this is how it has always worked. There never was a different and easier experience. That's why Windows 8 is such a surprise -- especially from a company that before now, regarded backward compatibility a top priority.
