Foldable phones are a hard breed for me to love. They cost about twice as much as a high-end smartphone, and having two screens and moving parts means more ways for them to break. Plus, these book-style models are bulkier to hold and often don't have the best cameras.

But the genre is evolving fast. And after reading David Lumb's first impressions of Motorola's new book-style foldable, the Razr Fold, I'm starting to give the style another chance. Its shorter, "passport-style" design is going head-to-head with Samsung's rumored wider Galaxy Fold 8, and it may not be long before Apple steals the spotlight with a folding iPhone.

So for this week's episode of One More Thing, embedded above, I can't help but poke at the potential of Apple's rumored foldable, which reportedly could be called the iPhone Ultra. Judging by some reports, Apple might have the experience running smoothly right at launch with an iPad-like interface when the device is opened. 

But good software alone doesn't make the price easier to swallow. It's expected to cost over $2,000. It might be an easier sell if you think of it as buying an iPhone with an iPad inside. I'm not ready to close the book on the idea just yet.
