As a college student in the 90's I was relieved to get a computer. When I finished college all of my documents fit on about three floppy disks. I think school today requires a bit more knowledge management and I can't recommend the Devontech products enough. Get 40% off during their back-to-school sale.
There's a lot of software you may still need but DEVONthink is the glue that keeps all of my information organized and easily found. These are unparalleled research tools.
