Technically that's correct (which as we all know is the best kind of correct), but really, how many consumers are buying a high-end MacBook Pro with 48GB or more of RAM? That's a very small percentage of the population. In these kinds of discussions, "consumer" is being used as a proxy for "something your average home laptop buyer might have". And a 48GB MBP is not that.
I know it's annoying, because a 48GB MBP is indeed technically "consumer hardware", but please understand the context and don't be pedantic. You know what the GP meant. (And if not, that's... kinda on you.)
