After countless issues and four replaced/repaired MacBooks in 2006 when I first encountered the white MacBook discolouration issues, I actually got a machine to last 18 months until the front edge of the top case started breaking off. This is widely reported on forums etc and appears to be a common problem. Apple Executive Relations offered to replace the top case, albeit rather grudgingly, so I had the work done by the Glasgow Apple Store. Imagine my surprise several weeks later when the new top case started turning BLUE. I have no idea if the repair was done with an old top case part with discolouration issues, or if this is a new issue. Executive Relations say their engineers haven't seen this issue and so can't help, which wasn't much use to me, but thankfully the work done by the Apple Store is still covered by a 90 day warranty (expiring in two weeks, when unfortunately I'm not likely to be in Glasgow). I'm going to get the repair done but after that really don't want to hang onto this machine as it's been a nightmare of poor build quality/components. Is there any legislation in the UK that states that after a certain number of faults an item isn't fit for purpose, or something like that? I feel that the number of repairs done to this machine is way more than a consumer should have to put up with, even though it's two years down the line. Failing that I'm going to sell the machine. It's clearly cursed.
