I don't know that "but they're just like the Catholic Church in the middle ages, so they must be an acceptable form of religion worthy of tax-exempt status" is really a good argument, if that's what you're going for. Remember that we (in the historical sense of my ancestors) responded to corruption in the Catholic church largely by leaving and then setting its remaining followers on fire and shooting them, in varying orders. I don't think the midaeval form of Catholocism would get any better a popular reception than Scientology... probably worse, honestly.
It's similar to the rationale for regulating sexually explicit content to a higher age in movies, I imagine: it's really obvious that you shouldn't murder people left and right so it's not really a big concern if kids see it on screen, but on the off-chance that there's a teenager that isn't already thinking about sex, and seeing it in a movie convinces him otherwise, the obvious fact that it's a private thing that you're not likely to get called out on is probably going to occur to him.
Admittedly I'm not a fan of any censorship, and got an annoyingly extensive sexual education at an embarassingly young age with no real side-effects, so I may not be reproducing the arguments perfectly. But, anyhow, it's not just craziness, there is a sort of method to the madness of the rating systems.
No, no, you let your kid watch that and next thing you know he'll be breaking three bones in the scrim and then knocking off for a pint or twelve with the boys in some dive in south London.
So lighten up, it wasn't ill-intentioned. And most of the apocrypha are either crazy or pointless (in my own estimation as well as the church's), so meh anyway. Hell, I dunno how most of revelations didn't get thrown out as well, it's pretty whack too.
(Side note: would have been nice if more monks had thought books of math and engineering were worth the effort, all we got was the half-assed job the muslim translators did of preservation. Better than the complete absence of the technical books in europe, but still. Anyhow, if you're going to be mad at the church for losing books, be mad at them for those, not the useless apocrypha bullshit.)
It is, however, backwards-compatible to a greater extent than, say, DVD, as you can take a bit of media from the last generation (a standard DVD) and pop it into a Blu-Ray player and it'll work fine. Trust me, trying to stuff a VHS tape into a dvd slot is a pain by comparison.
Anyhow, I think that people buying new playback hardware are buying blu-ray (because why not? it still plays DVD), there's just no rush to upgrade their existing libraries or their working players. Speed of replacement is slower than speed of "shiny new thing", but it'll take over eventually.
*I assume it's elegant, since this is like the 4000th time they've refined the general 'tracking' idea but only the second or third version they've put on the market.
(For reference, I use Ubuntu for tooling around on the internet at home, Vista for gaming, XP on my office machine so the department tech won't hate me, and 95 on my equipment machinery because of god knows what compatibility issues with the X-ray control software.)
(Side note - Never try to get 95 to support USB, no matter how modern the hardware is and how much you hate juggling floppy disks full of plain-text data. It's not worth the emotional anguish.)
Just saying that those courses are in there because they're an important part of electrical engineering, not because they felt like tossing some extra crap in for accreditation. Sure, you can do nothing but be a non-calculation-intensive code-monkey with an EE degree, but only in the same sense that I have the option to make really good pizzas for a living with my ChE degree.
