Sure, and I could also compare them to 8 Track Tapes or other forms of
media.
Compared to chipping bits out of stone, 3.5" floppies are fragile.

They're not hard to snap in half, have done that on occasion with media
where the dye has given up.
Interestingly, though, if you put them through a shredder (I have one
that handles CD/DVD media), often times the plastic doesn't come apart
and you end up with interesting designs.

Wrong, it does. Over time the dyes (especially in cheaper optical media)
will fade and you'll start getting read errors.
I do have some optical media that that has happened to.

I actually have two CD-ROM drives like this. Both of them are in the
pile of electronics that are going to the recyclers.

But the new stuff referenced at the engaget link above is said to be more
durable than stone, which is also pretty cool.

Yeah, that is pretty cool. :-)

As my mom tells, I used to crawl around the house holding cassette tape with
one of my tiny fingers. While the cassette in question remained inside a
drawer. Thus, tape around the house.

And pressed CDs are MORE prone to degradation than CD-Rs. Hence, making
backups of bought software/music is indeed a good idea (DRM permitting).

No disagreement there. First thing I do on the rare occasion I get a
music CD is rip it to MP3. Of course it usually ends up on my iPod
then. :-)

How do you work that one out?
I have numerous CD-Rs which are no longer readable, but I don't possess
one single pressed CD which is unreadable. And I own CDs that were
purchased before CD-R was even *invented*!
Just for completeness, at work we've recently had serious trouble
because some CD-R archives of really old data are now unreadable. But I
have Windows 95 CDs that predate them and still work.
Think about it: CD-Rs work using a light-sensitive dye. It makes sense
that it could fade over time. Pressed CDs use a layer of aluminium
metal. How is that going to fade?
