The answer comes from up high. When a MacRumors reader emailed a general Apple line about why not use a 32GB RAM option . he got a surprise response from marketing chief Phil Schiller himself . Schiller said : To put more than 16GB of fast RAM into a notebook design at this time would require a memory system that consumes much more power and wouldn't be efficient enough for a notebook. I hope you check out this new generation MacBook Pro, it really is an incredible system.
So this would seem to undermine any speculation as to whether the new MacBook Pro’s performance upgrades mean a bump in memory isn’t neccesary But Schiller’s reply does point a more concrete finger at battery life, which Apple tends to prioritize over other benefits in its notebook lines.
