In my opinion the MacBook pro is far supierer to the macbook air. Yes its a bit heftier BUT it has a disk drive, the screen is bigger, the hardrive is much larger, and it is noticeably faster. I say go for the MacBook pro but I'd your on a tight budget you should be able to work with the MacBook air.
If you're only going to use it for work, get the Macbook Air and an external disk drive at the side. Portability ftw, I say.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
