First, the fan runs when it's charging. Every other device on Earth can charge silently when turned off.

Second, the keyboard is not just small but also oddly arranged. Maybe some people can adjust to it, but for me, dear lord do I despise the letter Q when I'm using it.

Third, there's something odd in the I/O that makes USB drives incredibly slow. The first thing I did was make a Windows 10 recovery drive on it (because I wanted to wipe it and run Linux). I kid you not, the operation took about 24 straight hours to complete. I haven't bothered profiling the system so I don't know where the bottleneck is. But it was a USB3 name-brand USB drive that I know is fast.

Fourth, they claim Ubuntu runs on it, but they took the typical Shenzhen approach of putting a modified binary on Mega -- in this case an Ubuntu ISO -- rather than upstreaming their changes or publishing source code. No way in hell am I installing a binary download like that as my OS. Maybe they are in the process of upstreaming and a future pristine Ubuntu distro will run on it. Meanwhile I'm stuck with Windows 10 (and no, I'm not happy with that, either -- I have no way of knowing it's not rooted, either).
