I read the article. I'm running Windows 8 right now, and have been running it for a while. Office 2013 was downloaded yesterday. I hate the lack of contrast in the UI (blinding white). I still have a handy backup to get back to Windows 7, though.
Apps are always easy to find. I could put them on the Desktop, pin them to the Taskbar, or pin them to the Start Screen. I can also search for them. (Though the Search oddly can't find Team Fortress 2.)
Files and Settings are a different matter. It takes an extra step to search for them, and not all the time do you now exactly what you're looking for, which is why enterprise search products exist so that employees can find what they need in their vast information stores.
"In fact, one could argue that Metro improves multitasking and reduces interruptions. Live tiles show dynamically updated data, with early examples including weather, finance, and calendar apps."
I've used gadgets for that, and if you consider checking the weather as an example of "multitasking," you seriously don't know how to multitask. Juggle a report in Word in one window, a PDF with reference information in another, an Excel spreadsheet comparing related item specs in another, and an IE window for searching for additional pullsheets in another. The funny thing about the Start Screen or Metro apps, though, is that it's hard to find THE TIME without diving back to the Desktop, hoping the app has a built-in clock, or heading to the Lock Screen.
Live tiles are little blurby reports. They can be useful and can help you decide whether to take further action or not, but they don't help in multitasking.
The other bad thing about the Start Screen and multitasking is that Metro Apps and Desktop Apps do not mix. On the Desktop, I know exactly what's open and can quickly mouse over for an Aero Preview or Aero Peek. However, if I'm using a Metro App as well (like Mail, IE10, or Remote Desktop), I can't easily switch unless I just blindly keep clicking the upper-left corner, Win-Tab, or Alt-Tab to the right program. We've effectively got two different Taskbars going around. I have enough of that between my own computer and an RD session, thank you very much.
...the fact that Metro is fullscreen should also help, not hinder multitasking because it ought to be quicker and easier to find whatever you're looking for. The Start menu shows 10 applications by default with support for up to 30 and if your desired program isn't offered immediately, you have to dig deeper into the All Programs list.
While the Metro interface is nice and big for people to clearly see what they want faster, if I need to launch an App but my search term is so nebulous that more than 10 possible programs show up, I clearly need to spend the extra 200 milliseconds to add another character to my search term. Or I just plainly don't know what program I even want.
For the record, two things that impressed me about Windows 8 is its battery usage and its startup and shutdown speeds, particularly for sleep and hibernation modes. But they're putting a lot of uncompromising UI and behavioral changes in place, creating a bifurcated OS that seems to regard Windows 7 with shame rather than the success that it was.
