"What you might not know is we've sold more iPads in the last year than the entire notebook lineup of all of the biggest notebook manufacturers," he said.
A little mental addition reveals that the sales of the entire notebook lineup of all of the biggest notebook manufacturers comes to about 122 million, versus iPad's 44 million. That's not more. That's less. A lot less.
Had he said "each" instead of "all," that would be more accurate, but not a terribly useful statistic. There's only one maker of iPad, but there are lots of makers of notebooks, and they outsell iPads by almost a factor of three. Just imagine if they weren't all crippled with Windows 10!
