The screen is huge and beautiful. I have had all the mainstream handhelds and a couple of the other brands. This screen wins for me with color.
The ui is ok. Not the most user friendly but of your getting into this device your probly not a novice when it comes to using this device. Would have like to see a couple more factory optimizations out of the box but nothing you can't fix if you know what to look for.
Controllers are comfortable at first. But if you have medium to larger hands they are too small. And medium hands playing over like 30 min leaves you wanting more girth to controllers. But this is all subject to preference.
My biggest annoyance is the version of windows on the device constantly has error message about gamebar which is not installed and not a bad thing if you ask me. But even if you disable everything that suggests gamebar, or try to download it, or the other multiple work around, occasionally you get the error comes up and interrupts your game. This is not the fault of oxp but the version of windows that is installed directly.
Overall it's currently the best device on the market if you like a bigger screen like I do.
