FYI... if you're just needing Word, Excel, Powerpoint without really advanced functionality, you can sign up for MS Skydrive, and use their web based Office apps for free. That also gets you 7GB of online storage for free. Works anywhere from just a web browser. It also works great on the iPad, so you can create Office documents on your iPad in exactly the same manner you would on the computer.
