I did indeed, I never said that SSDs are a replacement for RAM, I just said that having access to 2.5GiB/s RW operations allows you to offload many things into the SSD, yes, thrashing is an issue, but it is much more insignificant at those speeds than disks.

I am not defending apple in any way whatsoever, I even mentioned in the first sentence of the comment. I stated that they are able to do that because they compensate with compression and SSDs, applications in the background can be thrown in the swap and the user will rarely notice.
