Samsung all but confirms iPhone Duo is goosing Galaxy Z8 sales

Key points

• Samsung has added a wider foldable phone to its lineup, likely in response to leaks about Apple's iPhone Duo. The wider screen shows video with less wasted space and suits reading documents and portrait-mode apps better than square foldable screens.
• Foldable phones remain expensive, but the gap with top flat phones has narrowed as flat phone prices have risen.
• Apple's iPhone Duo costs $2,000, while Samsung's wide model costs $1,900 and has been discounted at some retailers since launch.
