#1. It is Apple's fault for selling defective computers to customers. Your reasoning is like saying Ford isn't responsible if it sells cars with faulty gas tanks if those gas tanks come from one of their parts suppliers.
Yes, it is Nvidia's fault for selling Apple faulty hardware. But, Nvidia is really liable to Apple, not to us. Apple is the one that is liable to us. We purchased the computers from Apple, not Nvidia. The lawsuit is quite stupid, given that it's being applied to computers sold by 3rd parties, not just GPUs sold by Nvidia directly to customers (Nvidia branded parts for sale to consumers).
#2. The lawsuit doesn't solve the problem. It's just a duplication, probably an inferior one even, of Apple's "kick the can down the road" pseudo-solution -- which is to replace faulty parts with faulty parts.
Apple's lottery approach (get lucky enough to waste tons of time, have tons of stress, and maybe even lose some data) where people have to have failure after failure in order to have the problem be truly fixed (a replacement laptop with a non-faulty GPU design), absurd as it is, seems better than the Nvidia suit's terms.
We're the ones who are paying for Apple's mistake. They chose to sell us those defective machines. We shouldn't have to deal with multiple failures in order to get resolution. In fact, we shouldn't have to deal with any failures due to a known defect.
I also find it supremely offensive that people are saying it's no big deal that we're to be left with time bomb laptops that cost a lot of money after a mere 4 years. Someone said the machines will be "quite obsolete". Obsolete? 4 years is nothing for some of us, especially poor college students. We don't have the luxury of buying high-priced Macbook Pro laptops every 4 years. Plus, the resale value of these units has tanked because of the defect. Again, we're the ones who end up paying for the defect -- not those responsible. I think those of us who paid hundreds extra for maximum-length AppleCare should also get something for our money, given that Apple extended the warranty on their defective GPUs for several years.
This is bad business.
