The verdict is still out on Apple's new iO7 operating system.
Reviews have been mixed, but there is no question what a 4-year-old boy named Jack thinks about it.
His dad recorded his son's reaction to the new operating system and posted it on YouTube.
In the video, Jack frowns as he says everything is different. When his dad tells him he'll have to get used to it, Jack erupts in tears, crying, "No, I don't want it."
Since being posted, the video has been viewed over 2 million times.
Jack's dad say his son was upset because he told him he would never see the old operating system again. He added that Jack was OK after using the new system.
