Happy with M4 Mini, although I recommend using a well ventilated M.2 enclosure instead of the integrated docks as I just had a 2TB Kingston die which I'm pretty sure was caused by "zero thermal forks given (chopsticks only)" UGreen hub design. Also can use as a laptop and replace screen/keyboard/whatever when failed/unsuitable. Higher resulting device longevity, especially with Asahi Linux making such great progress. https://github.com/vk2diy/hackbook-m4-mini
