Like the other commenter mentioned, you can upgrade the 13". It's pretty common for laptops to come in two classes: smaller with a focus on portability and larger with a focus on performance.
There's a reason why a lot of us sat on the sidelines and were looking forward to the 16". There is no slippery slope here, the differentiated product lines 100% make sense.
Edit: there is another class I could see making sense - desktop replacement. Those chassis' tend to be pretty chunky because they put desktop parts into a laptop. Think 10 lb laptop with a battery that lasts 20-30 minutes. But I'm not sure if the market is large enough for them to pursue it.
