The problem I have with 16GB as a upgrade is that the base model is widely available and often on sale. 16GB does exist as preconfigured option, but it is a lot harder to come by. It's mainly sold as BTO, which means you have to pay full price. That makes that extra 8GB of RAM ridiculously expensive. I mean it's already ridiculously expensive, but the fact that base models sell with huge discounts increases it even further. I will NEVER EVER pay for this upgrade out of sheer principle. I'd rather switch to another system.
