So I keep comparing it to Mint since they're both Debian and cinnamon. This one however has a cool dark theme, thats all that I can differentiate from the two.
Is this distro "good" (as in reliability, privacy etc.)?
What does this distro bring to the table that Mint does not?
(Also is there an Ubuntu Cinnamon or is that just Mint?)
A lot of distros are basically the same and bring nothing, there effectively spins. Just take the base distro you like and install the desktop environment you like.
No, RoboLinux is the worst kind of linux distro out there. Tricking windows users - mainly small business - into a "pay as you upgrade" migration of existing windows infrastructure to linux.
Robolinux advertises "StealthVM" which is just a couple of skiddie VirtualBox scripts that manually setup a VM to migrate an existing Windows install.
I don't know anyone who's using Robolinux, but I can't see it being any worse that any other small distro.
I've used Mint since version 10 and it just gets better with each release. Mint 17.2 is polished, very usable and solid. Easy to customise, if that's an issue.
I tried Ubuntu Gnome in virtualbox and it looked very nice, but after a week of playing around it just didn't feel like I could live with it as my main distro.
I see you've already been on Distrowatch, so why not try a few distros until one clicks. You've nothing to lose, but your time.
