Hello, I'm pretty new here, but joined because i enjoy Apple products. Right now, i have a Dell computer and am looking into buying a mac. I'm pretty sure I want a laptop but don't need one right away. Im in HS and want my new laptop to last me at least through half of college. I'm thinking about the macbook air when the 2nd revision comes out or just the plain macbook but not sure. Any help would be appreciated. Thanks
