Which laptop should I get for college?

I'm in between the three:

13inch MacBook Pro with 8GB of Memory
13inch MacBook Pro with 16GB of Memory
13inch Lenovo Yoga 2

Price isn't the biggest worry for me (I actually have a scholarship- but I would prefer not to spend that much over the $2000 limit unless it is worth it)

I'm going to be a Earth Sci/ Geology major and the academic department said anything is fine.

I'm leaning toward the Macbook- in which case, is it worth it to have 16GB of memory?

Also I'm looking for something to last me through college and perhaps even through grad school.

and if I get a Macbook, I will configure it to an i7

The 13inch Lenovo Yoga 2

13inch MacBook Pro with 8GB of Memory is enough wow amazing I LOVE GEOGRAPHY AND COMPUTER BY THE WAY
