If the @ sign burns your eyes, try reading it backwards like a Java package name: com.openssh.foo or org.putty.bar.
and when I want to use a computer on "me time", I prefer the recliner.
I want to agree with you. For a while, I ran my PC through an HDTV and put the keyboard on a tray table. But if your family's primary PC uses the living room TV as its monitor, then you can't watch TV while your kids are doing typed homework.
If you use a normal PC, nothing but inertia prevents the system from dual booting steamos and the desktop of your choice.
And it is inertia that makes it so inconvenient. I mean this literally: a desktop computer at rest stays at rest unless acted on by an outside force, such as by being carried into another room. Most people don't want to have to move a desktop computer from the desk to the TV to play a game and then move it back to surf the web.
my Mint running i7 in the living room
You happen to have your computer desk in your living room. Not everybody else does. Some people keep the computer desk in another room in order to preserve some level of peace and quiet.
"I find television very educational. The minute somebody turns it on [too loud], I go to the library and read a good book."
Good luck with that when your library is closed evenings and weekends.
Did it click in that "Canada post" isn't american?
Canada Post is both American and not American because though Canada != USA, they're both on the continent of North America. Though Canada shares some mentality with Europe, it shares other mentality with its southern neighbor.
Parcel guys have to solve the "travelling salesman problem" in their head
I don't know about Canada Post or USPS, but UPS has computers to do that routing.
I also know for a fact that the HDMI out on my desktop/gaming system supports audio and 1080p to the TV. From there it's really trivial to set a desktop up [...] and put it on a TV.
I've said this on Slashdot for years. But often, I've been told that the majority are unwilling to build or buy a second computer to dedicate to the TV. Whether computers that ship with SteamOS will change this is still unknown, but OUYA (an Android/Linux-based game console) hasn't made much of a dent.
Why not get yourself a new midrange graphics card for your Linux box and just install the desktop Steam client?
Because it's not always convenient to run long HDMI cables and a bunch of USB hubs from the computer desk through a wall to the TV. Or because one's existing Linux box is a laptop or small-form-factor desktop that doesn't take graphics cards.
