- very inconsequently built
- repository is not full debian repository
- actually, its not rolling release; its "wave-release", which means it may break compatiblity with debian itself.
- (debian specific) no ppa
- a lot of automation missing, which you expect from for-noob distro
it feels like debian, behaves like debian, so why not debian instead. But debian is definitely not for-noob distro. A lot of functionality one expects on Ubuntu, is RTFM and "do yourself" thing on Debian.
