I think it depends on your major and how you use it. I went to college for computer networking and had to have a windows laptop. Now i am a writer and am switching to an iPad because of the dictation and dragon software. My wife is going back to school and mostly uses her iPad and seldom uses her laptop. There is nothing wrong with getting the iPad and a 400.00 windows laptop. I am not saying its the best option for all, but for us we almost never use our computer anymore, but they are there if we need them. I just sold my macbook air to pay for the new iPad and kept my cheap windows laptop.
So all and all it depends how you use it.
