I’m wondering how many Tablo fans are also Ubuntu Linux users?
It seems to me that there may well be a great deal of crossover here, as TV cord-cutters might well be Microsoft cord-cutters.
@brentdollins although I have used Ubuntu in the past, I am cord cutting from Tivo. I had Microsoft a long time ago, but it was not for me.
Only used Ubuntu in the past. Still with M$ now
I’m a Linux user front to back. Not necessarily a big fan of Ubuntu (distorted misdocumented Debian). My wife has been a Linux user (she’s non-technical) for about 16 years or so.
Plex PMS running openSUSE 12.3 on a Lenovo Q190 (Lifetime Plex Pass)
TabloTV dual tuner (Lifetime Guide), indoor “leaf” style antenna with amplifier (we’re 40+ miles away from the tower)
4 x Roku 3
Netflix
Amazon Prime
3 x HTC One M8 (Android) phones with Plex
Internet and Phone through ATT U-verse (no TV)
I never created a Microsoft cord to cut (believe it or not). Prior to Linux I used an Amiga, prior to that, CP/M.
MS cutter as well for three years, OpenSuse shout out here, thinking of diving into Gentoo.
Installing Mint LTS versions for non-technical friends and family members for as long.
90% of users just want a browser for Facebook, eMail, etc.
Arch Linux with KDE on a Dell E4300 for me 
Used SAGETV for about eight years. Loved it, but Google bought them and shut it all down. When both of my extenders died I had to move on. I tried WMC with two XBOX 360s as extenders. Terrible; worked pretty well at the server connected to a TV, but the extenders failed almost daily. Finally went to Tablo, on a Ubuntu server in the garage, with Plex & Chromecast on two TVs that work great, an old Roku N1101 on an old HDTV with component input (never could convert HDMI to component that would work). But I know nothing about ubunto; my son set it up. But I can say it has not needed a minute of support in three months,so Plex and ubunto have been great, except for when the Tablo channel was out for a couple of days.
