MacBooks are out for me now that they have the touchbar and bad keyboard. I currently use a ThinkPad and it's pretty good, but the touchpad is mediocre at best.
I think a ChromeBook with really first class support for Linux apps is very compelling. I run Linux in a VM on Windows 10 on my ThinkPad and it's a great setup. A ChromeBook would be a very similar setup but probably with better native OS integration (for example they are exposing the Linux filesystem in ChromeOS's file browser) and this would all be a first class use case supported by Google.
