I've had an oryx pro for about 8 months now. I've spent zero time trying to get Linux working correctly. You can go from zero to programming, playing games, etc, in about 5 minutes.
I have run a Zimbra server for several years now, it's a full size enterprise grade email server.
I can run it on a $10 droplet from Digital Ocean. $10 is kinda high just for my email, but the bonus is I host _all_ my family's mail. Wife, kids even mom and dad!
It's been nice not being concerned about email privacy. Zimbra is a great piece of software. I think more people should look into it.
