Apple has reportedly abandoned plans for a foldable "iPad Ultra" following years of disappointing sales performance for the iPad Pro. The claim predominantly comes from the Weibo leaker known as "Instant Digital," who posted the remark in response to a question about whether the iPad would join a rumored "Ultra" series of Apple devices.
I think as foldable and/or flexible screens progress there is some opportunity for more interesting designs.
Honestly, anything to mix things up again in the laptop/phone/tablet space. Devices have gotten boring.
