We have had this tax for a couple years here in france. AFAIK any device that could possibly display a TV program makes you elligible for the tax.
Most people try to get away with "I don't own nor watch TV I swear!" though.

The best entertainment related tax in france is still the tax on blank media. Whenever you buy a CD, DVD, Hard drive or whatnot you get to pay a Tax to support the recording industry. Because we KNOW you are going to pirate stuff, you thief!

As far as i know, TR is the first artist ever credited with having used a Mac in the actual recording process (citation needed). He allways has been a great supporter of apple products, and it looks like a major turn down. I wonder if he will make the move to open source software? He's a geek for sure but not the kind to enjoy hacking into JACK all day long.

At least we can hope for swift reaction if the president elect of the USA is unable to listen to music while on hollydays.

Windows seems to be a good-enough choice for any military application. Except that your average security guy will warn you of the 'security through obscurity' : closed source doesn't mean safe source. I do think the U.K. had to review the kernel's code a fair bit before doing that, or else we are in trouble.
I am more concerned by the fact that the windows kernel is somewhat poor security wise, and that the average windows developper can't do shit if its program doesn't run as root err administrator. Trying to mingle Windows and security is difficult for this reason alone.
