A split image of Steve Ballmer and Mark Zuckerberg
Mark Zuckerberg (right) took on Apple's latest big product, but Steve Ballmer's criticism of the iPhone shows may be a dangerous play.
  • Mark Zuckerberg trashed Apple's Vision Pro this week and called out Apple's "fanboys."
  • But Zuckerberg isn't the first to vocally dismiss an Apple flagship product.
  • Steve Ballmer infamously laughed off the iPhone at first.

Mark Zuckerberg posted a takedown of Apple’s just-launched Vision Pro this week, criticizing its cost, specs, and called out Apple's "fanboys."

It was a surprising swipe from the Meta boss at one of his biggest VR rivals. But if history's any indication, underestimating Apple is a risky play.
