I use Linux a bunch. Not for everything, but I like it when a device that I own is running, or can run Linux. I installed Linux on my PS3, back when that's what PS3's Open Platform meant. I was excited years ago about having a car stereo that would run Linux. It's not that Linux is a great system, it's that I really dislike closed proprietary systems that presume to control how I use my hardware.
Not too long ago, I finally got a high-def display for my living room, after far too long in the 480i wilderness. Oooh, crisp details at last. I started getting Blu-Ray disks from NetFlix. Fancy!
And then Sony decided to un-open the PS3. So much for the "It only does everything" ad campaign. It seems the PS3 only does what Sony thinks is OK this month.
By the way, do you recall when Sony was installing malware on legitimate users' machines? I don't trust Sony to decide what's OK.
So, I'm in the process of building a home theatre pc. It'll run Linux, of course. Well, that seems like a natural choice, but the options for playing Blu-Ray disks under Linux are convoluted, scary, and somewhat shady.
I'm OK with convoluted (see above where I mention using Linux). I'm peeved that we're living in a world where watching a movie is a tightly controlled activity.
