Hello, I am trying to decide between Lenovo Carbon X1 Gen 6 and the MBP 2018. The Carbon is 1.13kg while the MBP 13" and 15" weighs 1.37 kg and 1.83 kg respectively. The battery life for the Carbon is 15 hours while that for the MBP 2018 should be about 10 hours. The MBP have higher resolutions but they do not have Nvidia GPU for CUDA computations. The Carbon has heat/noisy fan issue and we don't know about the MBP 2018 yet. If the MBP 2018 can use Nvidia GPU and eGPU under Ubuntu Linux, then the MBP 2018 is OK. However, so far it seems that MBP+eGPU+Linux+Nvidia do not seem to work well.
