On Monday, June 3, 2019 in San Jose during the WWDC inaugural speech (Apple Worldwide Developers Conference), Apple has unveiled the new operating systems for its devices (phone, tablet and computer). The company also introduced a new Mac Pro and a new screen, the Pro Display XDR. The public had an unexpected reaction when John Ternus announced the base price for the screen (sold separately). The display value without the base starts at $ 4999, but if you want to put on your desk, you have to buy the base, which costs $ 999! Listening price, the audience laughed without sense if it's a joke.
