There exist other, larger ThinkPads that accommodate user upgradable RAM slots for those that need it. No product can be all things for all people. For example you can get the P1 with 64GB of memory. As someone who splits his work between a 64GB workstation and a 16GB ultraportable, there are a ton of use cases where 16GB is a perfectly acceptable amount of memory. That said, 32GB of soldered memory is feasible in a ultra-portable these days so it would be nice for Lenovo to get with the times.
