I won’t link to the middleman vendor.
Some press release details are here: DeePoon Unveils ARM Powered, All-in-One VR Headset.
If Samsung did that — with all of the VR access the Gear VR has, plus the ability to add VR apps like JauntVR, et al — for US$499, it’d be worth it.
But an unknown Chinese company without any of that VR access? No sale.
