The iPhone Duo on Amazon (paid link) landed fresh this week, bringing foldable flair and all-day endurance, while the SE (paid link) remains a pocket-friendly relic from a previous era. At nearly twenty times the price, the Duo is a flagship statement that the SE simply doesn't attempt. If you need a screen that adapts and power that never quits, pay Apple's price; if you just need something light and cheap, the renewed SE still works.
