I am unsure of what laptop to get as i am going to university next year and my current one has pretty much had it.
Am currently thinking about a mac but not sure.
I'd like something that is easy to get around, has excellent battery life and one that is going to do any task thats needed.
Also need a lot of space for pictures (approx 2000) and music (approx 4000)
Have you checked what your University is recommending?
Also check for any specialized requirements that some of the majors you're considering might have.
For example, the Univ or Texas at Austin, College of Education requires an Apple computer with OSX.
