I just got a smart TV, but I've left it entirely disconnected from the network. I connected a Debian box running XBMC to it. I trust that machine far more than whatever is running on the smart TV. The rule for my trusted network is: if I don't have root, it's not trusted. And root is a necessary, but not sufficient condition for trust. For example, my Kindle is rooted, but I still don't entirely trust it since Amazon still has remote control over it.
Also, remember that in a city, you can't legally take your gun into most stores or offices. If you illegally take it in, you are subject to a felony and loss of your CCW permit.
Which city/cities are you talking about? Private businesses have to post a no-gun sign in order to prohibit lawful concealed carry on their premises, and illegally carrying into one of these businesses is usually treated as a matter of criminal trespassing - a misdemeanor (although you'll still lose your CCW permit). Government buildings are a different story - federal buildings are always felonies, although state buildings can differ (e.g. Ohio-> felony, Oregon-> OK w/ permit).
The rest of your comment is excellent advice for future CCW holders. For anyone with a CCW, always remind yourself of your responsibility every time you put on your weapon.
I have a Kindle paperwhite (a "normal" kindle). I have rooted it, and I am able to ssh into it. It runs Linux:
[root@kindle root]# uname -r
It looks like it has most of the GNU stuff, so in that sense it is more familiar than Android.
I'm not disagreeing with you - it's a device built for a single purpose. It just uses a general computer to do so.
and it can never be physically taken from you
Me and my $5 wrench disagree.
I think that we're going through a similar phase with computers. Right now, there is little regulation, and the companies are taking full advantage of that. However, I think that more and more people will get pissed off at the tracking and invasion of privacy. Many people fought very hard to bring in the reforms of the progressive era. I hope people today will fight to bring in the reforms needed to keep up with today's tech.
