Running windows... Parrallels?

Hey.

I read the stick thread, and noticed that parrallels "Requires alot of RAM"... I Have a new macbook with 2GB of ram. Heres the situation... I'm taking a class next semester that is on Microsoft Access (ew). So I am going to have to boot up in windows to run that program. That is the ONLY time I will need windows. Should I just use bootcamp as opposed to parrallels? Looking for some general tips/feedback. I realize that bootcamp requires a reboot. If I go into OSX, get my files onto a USB drive, can I then boot up and use them in Windows? (i'm just trying to think this through from a school perspective).

Thanks

Wait,
shoudl I just get cross over mac? lol, that seems like the golden key.

nevermind... it actually says Access 2003 (copy I own) doesnt work with it.

I use Parallels with my Macbook 2ghz C2D with 1GB RAM, i need to run Access and Excel XP for college and it runs pretty fast takes a while to load up but once it's up it runs fine.
