quote: Double desktop (Windows 8 UI vs. the traditional desktop)Why? creates interface slowness and cognitive dissonance
quote: Switch to single windowingWhy? Hard to remember what you have open for complex tasks
quote: "Flat" look of Windows 8 UI tilesWhy? Hard to tell where tile boundaries are, icons are more likely to be less distinctive
quote: Photo/graphic heavy UI themesWhy? While nice to look at they convey information at a lower density than "uglier" themes
quote: Live TilesWhy? Third party developers show less sophistication than Microsoft, toss together confusing tiles that don't enhance usability or understanding.
quote: CharmsWhy? Harder to use on traditional devices, are hidden (and thus forgotten), and don't work universally across Windows interface, so they confuse.
quote: GesturesWhy? Nielsen says the gestures are error prone and overly complex, such as the multi-step gesture to reveal running apps.
quote: Tablet UI for DesktopsWhy? The above problems are less obvious on tablets, or in some cases not problems at all; he argues "One Windows" is a bad strategy for Microsoft
quote: The reason you can only tab through the running apps from right to left is synonymous with pressing the "back" button on your web browser. Similarly, if you press and hold the "back" button in your browser you'll see a list of all the sites you visited and can pick one to revisit without having to tab through each of them.MS basic paradigm here is based around abstracting a web browser - which is probably the most universally familiar way of interacting with a computer for most people. Even granny can work a browser.
quote: I find your analogy perfect. However, you forgot to mention the best part : browsers have tabs, allowing fast switching between different web pages. If MS really did create the paradigm based on a web browser, it was thinking about a stone-age browser.
