I ordered a new 27" iMac in January. It was plagued with serious issues from the very beginning and regularly crashes without warning. Needless to say, I've lost significant data, and cannot use the machine at all because it is too unreliable.
I started calling Apple Support within a couple of weeks of delivery. They put me though a series of time consuming but ultimately useless steps. Each one took most of a day, and it would be a couple of weeks before I had time to spend another day dealing with my defective computer, so after several operating system re-installs and one week at the genius bar wiping it and again reinstalling the OS - the problem has not changed but now they are saying that it's out of warranty.
Having spent months dealing with this and still not having a working machine, I've asked them to either replace it or issue a refund, but now they tell me that it is out of warranty, even thought they are still trying to figure out what the issue is. I've spent approaching hundreds of hours attempting to fix this problem, and re-setting up the machine after numerous re-installs. When I asked what my alternatives were, they actually suggested that I could sell it online!! They delivered a broken machine (that I paid nearly $3,000 for) and they have not been able to fix it, so they suggest I sell it (at a huge loss) to some unsuspecting person who will have even less claim to a warranty that I do.
I'm outraged and disappointed. Apple makes a lot of fuss about their customer service and reliability. It's all hype.
Buyer beware! If there is any indication at all that an Apple product is not working perfectly - return it for a refund IMMEDIATELY. Engaging with their support system is just a way for them to string you along until they wash their hands of the problem -- leaving you with a very expensive piece of junk.

details on the machine:
NVIDIA GeForce GTX 775M 2GB GDDR5
3.4GHz Quad-core Intel Core i5, Turbo Boost up to 3.8GHz
32GB 1600MHz DDR3 SDRAM - 4X8GB
3TB Serial ATA Drive @ 7200 rpm
