Bing got a quick but notable shout-out during Apple's annual Worldwide Developers Conference on Monday morning.
You know what didn't? Google.

Wrapped into the list of updates coming to the Siri voice recognition software, Craig Federighi, Apple's senior vice president of software engineering, rattled off some of the sources for search results.
Along side Twitter and Wikipedia, Bing was highlighted as a primary (and perhaps the default) search engine.
The quick and quiet mention of Microsoft's search engine was said to spark "some low murmuring" among developers in the keynote hall at Moscone West.
For now, that is basically all we know concerning the subject.
The battle between the two tech giants continues to escalate -- both on sales charts and in courtrooms worldwide.
Apple execs were certainly vocal about its sentiments towards its neighbor in Silicon Valley, repeatedly slamming Android during the keynote (as well as Microsoft and other tech companies, to be fair) on everything from performance speeds to fragmentation in its ecosystem.
But perhaps the omission of Google (either during the presentation or in the software altogether when it rolls out this fall) is more significant.
