A lot of Canonicalers are getting the Dell XPS 15. It's practically a macbook clone. The main difference is the battery life - with the smaller battery it's like 3.5 hours, bigger battery is like 5 hours. But that's with a quad Core i7, and 16 GB of RAM. I'm super happy with mine. I think most of the difference in battery life is just software at this point... Apple definitely has some magic sauce in there.
