It's a good model, however take note:
If you want good battery life on this model, you MUST opt for 24+72Wh battery which increases weight
Also, there's no display upgrade option (higher sRGB panel) unlike T480
QC might not be as good as T480 / other premium business laptops like Latitude 7490

2500U and 2700U are basically same, only difference is iGPU performance. KBL-R / WHL ULV and Ryzen mobile APU have about the same multi core performance, however it depends on various factors like cooling, firmware etc
