I wonder if Microsoft's numbers (which we're assuming they have and use) aren't skewed by the usage patterns that they create, with users taking the path of least resistance for the given options, which are themselves sometimes paths of a-fair-amount-of resistance.

For instance, I frequently switch windows in Win7 with Alt+Tab, but also dip into the task bar quite often to click the Word icon, then identify the correct Word document open, then move the mouse to the document... neither of which are particularly efficient.

The only approximate solution I can think of would be having a touchscreen above my F-keys to select apps with. I can imagine MS have no data on how well that would work.

If only there was an OS where you typed what you wanted in an omnibox and it would just work...

Are you talking about Alfred on Mac OS X?

I LOVE Alfred - it beats Spotlight hands down! The best equivalent I've used for windows is Launchy. Honestly Alfred has changed the way I use my Macbook :)

I'm gonna guess he's talking about ChromeOS.
