Going to 16 GB base is a waste. It's simply not necessary.I think the real point is that nobody is suggesting that Apple should put the base price up by $200 just so some of us can have 16GB.
After 8-10 years of 8GB as a base - Apple should, by now, be able to offer 16GB without increasing the price. Just as, over those years, they've regularly improved almost every other specification while Mac prices have barely kept up with inflation, and just as, in earlier years, they've gone from 512MB to 1GB to 2GB to 4GB to 8GB.
12 GB base is the perfect solution here, as it would make both entry level users (or at least most rational ones) and beancounters happy.
