I am currently a college student in computer science at Depaul. I am going to be studing network security. I need to buy a laptop so I can work on my homework besides at home or at the labs. What OS system is best given my major? I am currently taking C++. Depaul (like U of Illinois ) is a windows school. I know Dell has been having quantity issues and I have only bought dells in the past because I like the custom ability so I do not know who make good laptops any more.
