I have one of the macbook pro systems with a failed (months after

Tangential topic reply: Depending on where you are, and how long ago
that was, look into your local office of fair trading, consumer advice
bureau, or what yours is called. You may find that manufacturers aren't
allowed to limit their warranty as much as they have done.
Over here, in Australia, if a manufacturer says they offer a 2 year
warranty, for example, that doesn't mean exactly 2 years. They're
obliged to have a reasonable amount of overlap. And the kind of
appliance, and its cost, get taken into consideration (what the
reasonable lifespan for it should be).
