When we published our review of the iPhone Duo, I got a lot of hopeful questions from my fellow Mini fans who took note of the cover screen’s Mini-ish 5.4-inch size. “Is this… a small phone that turns into a tablet?” they asked. And I’m sorry to be the bearer of bad news, but no. The Duo is not the small phone we’ve been looking for. I wish it was. I like a small phone. I own an iPhone 13 Mini that I refuse to surrender, even though it barely lasts a full day. But the Duo is thick and heavy.
