I can't tell whether this is serious or not. Surely adding independently configurable memory/storage combinations won't confuse the user, any more than having configurable storage options don't make the user confused about what iphone to get?
Configuring your iPhone storage is something every consumer has a concept of, it's some function of "how many pictures can I store on it"? When it comes to CPU/GPU/RAM and you're having to configure all three, the average person is absolutely more likely to be confused.
It's anecdotal, but 8/10 people that I know over the age of 40 would have no idea what RAM or CPU configurations even theoretically do for them. This is probably the case for most iPad purchasers, and Apple knows this - so why would they provide expensive/confusing configurability options just for the handful of tech-y people who may care? There are still high/med/low performant variations that those people can choose from, any the number of people for whom that would sour them away from a sale is vanishingly small, and they would be likely to not even be looking at Apple in the first place
