Dell Chromebook 11 worth it?

Hello All, So I am looking at getting a cheap Chromebook for university as I don't want to take my MacBook Pro with me to work or university as I work on my documents. I don't want to spend a lot on what essentially is a word processing machine for me and was wondering do I spend an extra £50 on 4GB RAM/32GB storage or stick with the 2GB/16GB RAM? I will be purchasing from dell directly.
