T470 is also an ultrabook as it comes only with ULV CPUs, but it provides a certain level of upgradeability. Soldered memory is not a real downside if 16GB is enough to run all needed tasks, as it helps to make laptop more lightweight and portable (1.144 kg !! and in the same time Carbon has a decent set of ports). So Lenovo provides a good choice for the folks that need to maintain something - T470 and for the users that do not do any hardware upgrading - X1 Carbon (gen5).
