Also second the X1 extreme. I bought for my machine learning projects and work. It comes with a dinky GPU (1050 TI w/ 4GB) which is useful for running experimenting with small deep learning models locally. I was able to buy mine with 64 gb and core i7 (i7-8750H 6 Core Processor) during Lenovo's cyber monday sale for around ~$1,800. It looks like Lenovo is moving aggressively and is selling their high end laptops at a discount to capture the Apple audience. A similarly configured Macbook pro would run closer to $3,500. I run pop os (ubuntu flavor) and it runs great. A couple of caveats. There is no linux driver for the finger print reader. Also it is super loud, anytime you do something intensive the fans start running. Additionally, you need to tune the laptop to get better battery performance. Usually, I disable the NVIDIA driver for general use which improves the life by 50 to 60%. And finally there have been some documented bios issues which have caused bricking. This is avoidable if you stay away from the touching the bios. Thankfully pop os makes switching between the drivers easy. Overall, its a great laptop. Love the keyboard and the power under the hood.
