EasyOS was born in January 2017, and since then there have been bits and pieces written here and there about how and why it is different from other Linux distributions. This includes some rather technical descriptions. What is needed is a simple plain-English list, so that anyone can get a quick idea of what EasyOS is all about.
So, here goes. Do note, though, that Easy is an experimental distribution, and the features may change, and some features are a work-in-progress. These items are not listed in any particular order...
Container-friendly
EasyOS is designed from scratch to support containers. Any app can run in a container, in fact an entire desktop can run in a container. Container management is by a simple GUI, no messing around on the commandline. The container mechanism is named Easy Containers, and is designed from scratch (Docker, LXC, etc are not used). Easy Containers are extremely efficient, with almost no overhead -- the base size of each container is only several KB.
Very fast
While using Easy, everything happens in RAM. App startup appears to be almost instantaneous, even very large apps such as LibreOffice startup in the blink of an eye. Ditto when starting a container, blink of an eye. Depends on your PC of course!
No ISO!
ISO for optical media is a legacy format. Very few desktop PCs are sold these days, it is mostly laptops, and none of those have optical drives. Easy is provided as an image file that can be written to any Flash-stick of 4GB or greater (and will auto-grow to fill the drive). Or, the file can be opened up and directly installed to internal hard drive.
