Best keyboard on a laptop for writing?

I need a new laptop, because my old "Blackbook" from Apple got very old and slow.

Aside from the usual web browsing and media consumption, writing is what I mainly do.

That's why I wanna focus specially on the keyboard. I liked the Macbook keyboard, but maybe there's something even more comfortable out there for guys like me who literally spend hours with typing text.

I know some great desktop keyboards, but since I'm often on the road, that's not an option.

Any recommendations?
