Yea that machine looks nice. USB-C charge and I/O. Great for travel (1 charger for phone (android) and laptop). Looks like a slightly heavier X1 Carbon. Otherwise everything seems the same!
Two non-size differences: 32GB is only available on the X390 and one of the two (I forget which) only has dual-lane Thunderbolt. The other one has full 40Gbps.
