As someone who has owned 4 of the 27in iMac's in question - 2010/2011 revisions. I can attest that the monitor issue has affected three of the four iMac's - whilst I always make sure I have AppleCare, the failures have happened both within the 12 month warranty itself and outside of the warranty.
The iMac I'm presently using has already had one LCD replacement, its also one of the models that has the AMD GPU issue - which Apple has acknowledged and is offering free replacements/repairs.
Now as a "savvy customer" I'll make sure my present iMac is fully tested for faults before AppleCare expires, have the GPU swapped out and probably moan and get the LCD monitor swapped out again whilst its under repair - and yes, screen impairment is noticeable 12 months after the last swap out, now with all this, I expect to get 5 years working life out of my iMac, after which its time for a brand new one with best specc's - here's the rub, I live close to a Apple Store, so can just pop in for repairs, others are not so lucky.
Further, under EU consumer laws all products are actually covered by a 24 month warranty - one that actually applies in this case, i.e., its a design/manufacture defect.
As with the AMD GPU, all Apple need to do was say we have a problem and offer to fix it if the machine was within a 36 month purchase date - rather than pour bile on the man suing, we should actually be asking what fool he dealt with at Apple, because if this was me and the machine was out of warranty I'd have probably managed to get it repaired by talking to the right persons.
Anyway, the guy is standing up for iMac owners, so whats wrong with that if Apple are at fault, which I personally can attest too with my own experience of owning 4 machines - a 75% failure rate being deemed high.
If you buy a car with a 36K/3 year warranty -- you had better believe if something goes wrong after the warranty expires, you most likely will have to pay for the repairs.
