The JingOS will immediately remind you of iOS or Deepin OS, and it looks like JingOS is using Ubuntu as it's base OS with KDE Plasma. There is absolutely zero wrong with that as they have themed it very nicely even though it is still an alpha release. You could also install any other Linux on it that will run on ARM.
JingPad has a Unisoc Tiger T7510 ARM chip with 8 GB of RAM and comes with a 8000 mAh battery (up to 10 hours of battery life is claimed). There is a 16 MP back camera for taking pictures and 8 MP front camera for video calls and online meetings. Storage is 256 GB UMCP storage, which can be expanded by MicroSD of 512 GB in size.
As per the roadmap of JingOS, there are plans for adding Android compatibility. This means you should be able to install Android or Android based ROM/distributions.
