What I like about this is:
- The developers are not attempting to reinvent the wheel.
- Material Design is well-regarded on mobile devices, and it's interesting to see what you can do with its ideas on the desktop.
- They clearly pick technologies that are the way forward on the Linux desktop: Wayland and Qt+QML. It's great that these things are maturing to the point that we can start leaving behind X and that it's clear that Qt has won the toolkit war.
- Focused approach of not (yet) supporting different distros, but (like Elementary OS) an attempt to focus on getting it to work well for one system configuration.
I hope these guys can put in the time and effort to make something out of this. It seems they are making a couple of good decisions already.
