No, it's NOT JUST A LAUNCHER. It's a logging daemon, a console input daemon, it's much, much more than just a launcher. So if for some reason (like power outage) your computer reboots, you can't just tail /var/log/* (or even specific logs, if you're familiar with your distro which most of us are). You have to use another computer to lookup some arcane command that's non-obvious (sorry, "tail /var/log/* IS obvious for anyone who has ever been a UNIX-world sysadmin), then you can proceed to fix the problem.
Now, personally, I'm willing to try it out on my laptop for awhile, and maybe, just maybe, I will consider deploying this in servers, in like 6 months after daily use by myself and my alternate. Otherwise we'll keep using 14.10 for now.
