Anyway, at some point this is going to get regulated, especially in the EU. They won't be allowed to use terms like 'purchase' and 'buy' without a specific legal consequence (like the right of resale). Until then we can only hope they get onerous enough to get on the radar of lawmakers.

I really like this idea. Make sure that words that if you want to claim to 'sell' something, you actually have to fulfill criteria that guarantee buyers' rights. It makes a lot of sense and would eliminate a lot of bullshit in digital distribution.

Amazon with Kindle books.

Jokes aside, I had no idea that OReilly gave PDFs with their books. I thought that was only something that much smaller publishers did.

Console games we'll take back if our disk tester says they're faulty.

If I meet the minimum requirements, if I can show bench marks, "prove" system stability, and run every other game in my library with the exception of this specific game, who is liable? Is it my fault that their game doesn't run on my system? That's an honest question, cause I don't know. I know that as a developer, if something I've written doesn't run on a computer that I consider it a fault in my software. Or, can at least recognize that an external force (i.e. a Bit Locker or something) will prevent that software from ever running due to permission issues, at which point a refund would be in order. I just can't wrap my head around not being viable for a broken product.

Valve are. As a matter of law, any seller is responsible for selling a working product. If Valve claim otherwise, they're lying, and probably breaking the law in doing so.
