Producers take the exact opposite approach, and use storage size as a price discriminator: a 64GB version might cost $300, while the 128GB is "only" $499, pure profit margin an order of magnitude higher than the cost of the actual storage.

You're answering your own question, storage is an easy way to do price discrimination, you can provide what is essentially the same device at two different price points, play to price sensitivity and better capture income.
Same with airlines, premium is usually ~2x coach, and business is ~2.5x premium. Is there a twofold difference in airline cost? I don't think so. But it serves to capture the less price-sensitive customers (as well as those with real needs which get fucked over by economy seating).
1. 1TB tablets have no fundamental value for the vast majority of customers

For example, a Dell desktop I had a while back was the lowest-end SKU, and therefore they left the AGP connector off of the board, even though the BIOS knew about AGP and there were the AGP solder points/vias on the motherboard. Had I had the ability to solder the dozens of points at the same time, I could have added my own AGP slot.
