I mean the prices you need to pay to upgrade the machines beyond the basis configuation. Currently Apple charges 240€ for 8g of memory, and 240€ for 128g of ssd

I mean the prices you need to pay to upgrade the machines beyond the basis configuation. Currently Apple charges 240€ for 8g of memory, and 240€ for 128g of ssd upgrade. The latter is 1920€/tb, while market prices are between 100€ and 300€/tb. A MB Air with 16g/512g is at 2000€, not counting Apple care, which is basically mandatory.
