I believe he means Excel 2011 for Mac.

Long time vim user here, and I'm considering learning emacs. How do you know it's the truth? And, how did you get started?

I've been using emacs since the 1980s, got started in school because it's the editor one of my early comp. sci. courses used. Tried vi a few times, and I still use it occasionally on systems where emacs is not available (this is one real advantage of vi[m] it tends to be on even the most bare-bones systems), but the separate input and command modes have never really felt natural to me.

I don't know how good Bing was, but Google put a lot of work into modernizing it's website after the launch of Bing so maybe they did see it as a threat.

Probably they just wanted to make sure they stayed ahead of Bing on all levels. Like Apple is doing right now with the iPad.

Adblock Plus for Firefox removes every ad you could ever think of, even the ads inside of youtube videos.
