Never understood why they don’t just offer RAM at closer-to-market prices instead of giving you a 4GB stick that will get tossed or sit in a drawer unused. Surely they’d rather make $20 on RAM instead of $0? It’s not like they refuse warranty service for unrelated parts because you’ve installed aftermarket RAM. I’d bet they could even get preferential pricing on qty purchases, so in theory it should be cheaper to get RAM / SSD upgrades through the mfg vs aftermarket…
