My Laptop’s Operating System

I have a school issued (white) MacBook 13′ that I’ve been using the last few weeks when I need a computer (besides my iPhone). It’s great that we have MacBooks for teachers and students. However, since we are also transitioning to Google Apps (thankfully) and everything I do is mostly cloud-based, I don’t see much of the shiny Mac OSX operating system.

Instead, this is what I see and use as my main operating system (Firefox).
