Lenovo pretty much blew it on this release IMO.. at least for me. Without power bridge and swappable batteries it essentially becomes an over priced E/L series with thunderbolt 3 or a second rate X series... when you could just wait for a sale and get an X series at the same or better prices.
Quickcharge doesn't make up for swappable batteries in the field. It just doesn't. Getting rid of the full size SD card slot further limits its use in retrieving data in the field. And whats up with still using v1.4 hdmi today. Its a 4k world folks and even budget machines are shipping with v2 hdmi now.
I would have much preferred they go the other direction... keep power bridge, move to hdmi 2.0, keep the full size SD and maybe add a mm thickness to improve thermals and include 28w CPUs like the 8259u/8559u as options. That I would buy. but I'll definitely pass on the Tx90 series.
