Since I'm here, I'll speak up as someone who has an iphone and uses node.
'percentage of iPhone owners using node' out of 'total iPhone owners'
'percentage of non-iPhone owners using node' out of 'total non-iPhone owners'
But since there are more than 3 times as many non-iPhone owners than iPhone owners, a Node user is more likely to not own an iPhone.
