Here's to hoping you mean Distribution instead of OS
And dw I know ubuntu is essentially a snapshot of debian testing + crud released every 6 months
I'm far from being in the 'ubuntu' camp
I just don't understand why someone would choose to create a new distro with the amount of choice out there. That's all.
After having done a year of packaging for a distro I have a few doubts such distro can really keep up with the likes of ubuntu/fedora/opensuse/arch.
FYI, I got the same thoughts about Mint linux. Just feel that we should have WM installers and teach people theres no need to completely reinstall an OS to change the way it looks. Are you seriously suggeting installing a dual boot over grub on EFI is harder than going: "sudo apt-get install mynewwm" and then choose it at login over your login manager? (and yeah I know that's a bit simplified!)
What? It's not a rolling release distro... I mostly use rolling release distros btw, great for dev, IMHO terrible for end users you where talking about
