Fair point as far as value goes. Although unified memory on proprietary architecture has distinct advantages, it's still squeezing the most out of the silicon (lower cost for the manufacturer) but at the loss for the consumer in that none of it is upgradable.
I heard apple had finally decided that it is right for consumers to have their own right to repair. They need to do that seriously if they want to keep some remaining market share. Value for the consumer not just for the producer.
