Typo in the first sentence:
"Nobody could argue that the iPhone has been a revolutionary product in the cell phone industry"
Surely there should be a "not" in there somewhere?
"Nobody could argue that the iPhone has been a revolutionary product in the cell phone industry"
Surely there should be a "not" in there somewhere?
I agree that it's ambiguous.
Example:
Tom argued about the war (unclear stance).
Tom argued the war was a bad thing (clear stance, Tom disliked war).
However, there may be a regional usage of 'argue' as 'question' or 'dispute' ("nobody could question/dispute the iphone's success") that I am unaware of.
