I assume you're a college student, so I'll respond as such.
I've found my macbook to be incredibly usefull for classes, but don't take for granted the usefulness of a pc on campus. Many classes require you to be able to have access to Excel, Powerpoint and Access for a variety of assignments. Just keep in mind you might need to use somebody else's pc or find the computing commons to get assignments done if this is your primary computer.
If you know all this and I just sound like a douche, then sorry 😛
