Depends how you use it. If you like using touchscreen capability, then you're gonna end up with a lot of fingerprints (you can also use capacitive stylus).
If you don't clean it too often it will get dirty... like mine....
You can use buttons/knobs to control it... or connect mouse... Interface gives you quite a lot of use options. Of course, I'm not discussing the UI usability, that's subjective.
And you could connect external bigger touchscreen if you like. Hope this helps, there is plenty YT video presenting this device anyway.
Good luck.
