I like the idea, but these KODI-based devices far too limited, they essentially only serve as media players for local content. For example, streaming Youtube is difficult and a poor experience relative using VacuumTube on desktop Linux. It's even harder to get a browser to work to stream from websites like Pluto and Flixer, especially if you want an adblocker. I haven't found a better option than an upscaled Linux DE on a mini-PC so far (however, see KDE Plasma Bigscreen).

Also, you can buy a more capable used ThinkCenter micro for less money, so the value proposition isn't exactly great.
