Hello SDN. I recently bought the new MacBook Air that has the 128 gb internal hard drive. I’m a sophomore currently so I’m hoping this laptop can last me until I finish medical school. I’m planning on using hard-drives to compliment the small hard drive space, but the tech guy who was selling It to me advised I just upgrade to a bigger space. I have until January 7th to decide. Is It a good idea to live off of hard drives for the next 6 years and save a couple of hundreds, or should I just upgrade to a bigger disk space?
