I can understand why the OP is feeling pretty aggrieved. You spend that much on a laptop and generally you expect it to last longer than that. I'm writing this on my 7 1/2 yr old macbook, which is still going strong. I've also had quite a few iPods and iPhones that have also lasted considerably well over the years. Overall, along with many others, I am very happy about the quality of Apple products and believe that on the whole, you get your money's worth. I therefore strongly recommend Apple products to my friends and family who have also purchased Apple products.
Ok, Apple is a business, an extremely successful one at that, and hasn't got there by giving away loads of free stuff. Ultimately it can't give a free replacement, repair etc. to every customer who comes in and has a little moan. Also, I'd imagine a number of those customers product's have probably failed because of abuse/mistreatment. It has to look after the cents (penny's for us UK guys

) for the dollars (pounds) to roll in. It has to be a bit ruthless and sadly that means not everyone is a winner and will feel happy about this. Yes, ok, in this instance, technically Apple are within their rights to say no sorry we can't help you.
HOWEVER, Over the years Apple has designed many fantastic products and people have ultimately fallen for the Apple ecosystem (I mean that in good way). With that people will expand their range of products from Apple and ultimately replace those, when required, with more Apple products. They are a very happy customer who is more than happy to shout from the roof top about how great Apple is. Now obviously everyone knows you pay a premium for Apple products so as soon as people buy in to it all the profits begin to roll in.
Apple has been very successful designing well made and eye catching products and has also importantly marketed these very well. It doesn't matter that they don't always have the very latest and greatest features, the iPhone is a good example of this. What does matter is that it has built up a very, very loyal fan base who are happy to keep paying the premium and spread the good word about Apple. This last bit is a key component as to how Apple has become the success it is today. Look at the queues that build up when a new iPhone is released. How many other brands have this kind of customer.
Apple has built this fan base and managed to keep it so loyal that it is not half as common as other brands, for people to constantly give up and jump ship. Now, I'm not saying the OP is the sole reason behind their success and that if he/she leaves the Apple ecosystem then they will suddenly fail. However, for someone who seems to be a very loyal customer and has purchased a considerable amount of Apple products, it would seem right that Apple recognises this and offer some sort of help to a customer that has helped it become what it is today. As a customer who had spent that amount on Apple products, you would imagine that in return, if such a situation as this occurred, this fact might want to recognised. To help the OP, Apple will help keep him/her happy, ready to spend more with them and also keep the good word spreading. It might be irritating to the OP who has helped contribute to their success that this isn't the case. Without its loyal fan base Apple probably wouldn't be in the position it is today.
All in all there are some instances where the bigger picture should be considered, this is probably one of them.
