I would say it depends on what you want to use it for and how portable you want it to be. The MB is far more portable than even the 13" Pro but it's less powerful. Personally I laugh at my son when he's using his MBP and the fans kick in where I'm sitting there with my MB absolutely silent. Generally I tilt my head to one side and say something along the lines of "what's that noise?". His answer is always the same "It's the sound a real computer makes".
My MB is used for web, email, SSH, media consumption and the occasional photo editing and it's absolutely fine for everything I do. He plays games on his which is why the fans ramp up.
