X1 Carbon: satisfactory performance, not for heavy use

Thinkpad X1 Carbon’s performance is reasonably good for both home-office and coffee-shop use.

The carbon does suffer a bit with heavy workloads, such as some long compilation (eg: GHCJS) tasks or IDE heavylifting (haskell-language-server). However, I can offload them to my P71 workstation at home (via manual ssh, vscode remote ssh or distributed build), and then use its binary cache (see here).

Per the pareto principle, the carbon is still a delight to use, although one must be aware of this compromise in performance, and not to mention memory (16G max RAM).
