I have one of these and they work well, my only issue is display support is limited. running this with a secondary display isn't currently support, you will have to write that yourself. also, window scaling and resizing of windows is not fully supported and you have issues with normal daily use at a screen that size.

if you are 100% sold on a single 3.5" screen and no gui, then it will work. outside of that, it's a novelty item
