I'm taking some classes now and one of my professors has written some software we can use to simulate some things. But duh, it's Windows software. I have a Windows notebook that weighs about 40 kilotons. I have a MacBook Air that weighs about five pounds. I've never experimented with Bootcamp or Parallels, so I'm not sure which way I should try or whether there's some much easier and cheaper way for the limited use I'm going to make of it. Windows is at least only $100 now instead of the joke $200 or more it used to be. I'm a little worried about space on this 128GB Air because I'm somehow down to 20-30GB. I can probably reclaim some more by deleting the iPhoto library (since I now also have a Photos library), but still it's getting tight. So if anybody has recommendations, I'd love it. I want to use these tools without needing to lug that heavy thing all over the place.
