Does anyone know whether and how this translates to other places in the world? For me, it's the most interesting with EU/Sweden. We don't have courts like this do we?
I don't think the courts really matter, what does matter are the legal guarantees. In the EU it is an explicit two years, so I think a situation like this, where a 9 year old appliances is being repaired under threat of legal action, simply won't arise as the customer has no legal basis for his claim.
So in practice the iron clad guarantee is only 6 months for most consumer products.
At least that's the interpretation of the law in the UK.
edit: small claims courts are quite accessible in the UK, so often the threat of small claims can get thing moving.
