Of course. Lots and lots. This doesn't mean it is a good thing.
Think of that American tractor company (John Deere) where you
can't exchange parts yourself because the built-in software will
notice and refuse to work. And changing that would be a copyright
violation... Think of those inkjet cartridges which have a chip
to stop you from refilling them with your own ink.
Taking always the "practical" route will lead us into full
dependency on three to four big corporations in a very short
time. We as consumers do have a bit of responsibility, too.
End or lecture ;-D
