Ask HN: Best chromebook for travel for frustrated MacBook Pro user?

I've used MacBook Pro laptops (usually 15") for 10+ years. The new thin keyboard is driving me nuts. Laptop use is 90% when travelling. At home/work I use desktops. Much of my work could easily be done in Google apps.

What's the best current chromebook for someone like me? 15" is not a dealbreaker. More important: light, awesome screen, good keyboard.
