Yup. My T480 was ~$2500 new on-sale. It has 2 batteries with one removable one, and upgradeable RAM.. features not found on the T490 or T480s.

I subsequently swapped the logic board from the iGPU to the dGPU + max performance CPU model, swapped the top cover for a magnesium one, HDD->SSD, and installed a better WiFi module. Also had to replace the screen once because I suck and broke it.
