@tomos: I'm not so sure the
"Adobe & maths" you provide is as completely off-topic as you seem to think.
The sort of obscene (read "profiteering") price-differential you refer to is usually the result of unfair pricing practices in a supply-chain controlled by monopolistic suppliers or their agents. Such practices are usually illegal
inside most Western economies, but not necessarily
between them - e.g., they seem to be common in otherwise unregulated "free trade" international transactions.
In fact, you theoretically (and usually in practice) couldn't
have such obscene price differentials unless there
was such a practice or supply-chain in operation.
The right to be able to sell "used" or pre-owned software is just a digital version of you exercising your existing right to sell (say) a piece of furniture that you had bought but might no longer want - that is what this EU Court of Justice decision confirms.
It's your
property (as per Locke's definition), after all.
Similarly, the idea of selling music tracks on mp3 files. If you got tired of your old vinyl LPs or cassette tapes, then you could always sell them. They are your
property.
Hmm...now, about ebooks...?
You always
know there is probably some kind of monopolistic, profiteering or restrictive trade practice in play the moment someone or some
thing (e.g., statute or local bye-law) tries to block you from selling what is legally your property, or where you can only obtain the purchase of a property through specific and artificially highly-priced agents.
Price-rigging and cartels (price-fixing agreements between suppliers) are monopolistic and usually illegal, but are common - they keep popping up.
It really does seem that you can't keep a good idea (for profiteering or ripping-off other people) down.
(Libor rate-fixing would seem to be the latest "exposure" of this - it's apparently epidemic and systemic in the financial system.)
This EU Court of Justice ruling on used software helps to redress the balance on the consumer's behalf.That's
two (i.e., that and the rejection of ACTA by MEPs) eminently sensible things to have come out of the EU inside the last 30 days
from unelected representatives. That must be a record achievement.
One could arguably have been most surprising. Two could be amazing.
