Cons
Con Not meant for VR
The product page doesn't mention virtual reality, instead it seems to be focused on augmented virtuality (overlaying virtual components into the real world instead of totally immersing the user into a virtual reality).
Con Looks cheap
The front of the device is quite large, looking like it is using a cheap screen that will have quite a lot of weight on the front of the device. No price has been announced, but the looks of the unit on trade show floors looks pretty generic and shoddily put together.
Con Bulky
The EP1 is blocky and heavy at 445g, thanks to it's included Tegra X1 SoC and cooling solution.
Con May be noisy with moving parts
The device has a built in smartphone chip that will need cooling in order to run Android games natively. This fan will cause some noise as well as moving air (from the top of the unit), which all may be a bit distracting.
