Ashland students can get a full copy of Microsoft Word (either Mac or Windows) from the IT department. If you have one of those tiny notebook computers without a CD drive, they will even install it for you.
Akron students don't get a deal like that, but I've found one that's close. It's called The Ultimate Steal, and offers a download version of the full suite for $60.
If even $60 is a problem, I'd suggest Open Office if you have Windows or NeoOffice for Mac. (Open Office says it works well with both Linux and Mac, but I haven't tried those versions.)
