I Returned My iPhone Duo

The author, an iPhone user since the iPhone 3G in 2008, recently purchased an iPhone Duo but returned it after six days, citing the phone's form factor as not being different enough from previous iPhones. They enjoyed the device as a developer, particularly the app Personal Best's Replays feature, but ultimately decided to swap it for an iPhone 18 Pro Max due to some downsides they couldn't overcome. The author appreciated the Duo's inner screen, matte finish, and compact shape when closed, but felt it was not worth the £2,000 price tag.
