Device looks like an overpriced flimsy mess from the teaser. Nobody bought into the AyaNeo DS because why would you buy a dedicated device with 2 screens that weighs more than my head. I'd rather attach a second screen to my handheld I already own and love. Any company that designs a dual screen device needs to make it with close to proprietary parts to play original games and emulate them at the same time like DS/3DS/WiiU. Otherwise this device looks useless and pointless.
OneXPlayer has teased a new gaming handheld. Called OneXSugar, it features a design similar to the Nintendo DS, featuring two screens. It also has what the company calls a "transformable" form factor.
