Apple hasn’t been been particularly transparent about the iPhone X’s numbers, in part because it’s a bit of a tricky new model. For starters, it’s a $999 phone. It’s also positioned against another premium iPhone model — which got a healthy jump-start on the pricier model.

That said, Canalys’ latest smartphone state of the union shows pretty healthy sales for the pricey new handset, putting it at 29 million units shipped in the fourth quarter of last year. That makes it the “world’s best-shipping smartphone model over the holiday season,” according to the analysts’ numbers.
