Since then, I've used the new MBP, and while it's a great machine I don't regret my purchase for a second. My only gripe with the Surface Book is that installing Linux is a bit of a nightmare (not sure if this is still the case), but I'm happy enough with running Ubuntu on a virtual machine.
I haven't spent that long trying it out but managed to get a Rails 5 app up and running without much fuss, I'm with you on it being a game changer.
Huh, I didn't think about that, but you're right. Yeah, I won't have to deal with slightly different shell tools that are bundled with macOS. I'm not saying those tools are bad, it's just that I'm so used to GNU tools. Also, the directory structures and the kernel interfaces will exactly be the same as Ubuntu. Good point.
Agreed about Linux too, I didn't even try (yet). But WSL is nearly there, I think the next update will be able to launch windows executables from bash (they say it's in the insiders build).
