I see the Concept UFO as a stepping stone but the only problem I see it having is the launchers. Since it's portable, I see it making setbacks that Nintendo did with their switch to make it affordable. If the people who are building are going all out, I'll say it'll be worth getting. The only issue I have it is the launchers on something portable. I'm thinking that background apps will mess it up depending on the hardware being used.
The launchers I see it running is Steam, Microsoft Windows 10 Store, Epic Games Store, maybe Blizzard, and a Alienware launcher if possible. I'm not a huge tech person but I can somewhat see the possible problems with it.
This has potential so the makers of this should take their time.
