My girlfriend told me about it. It's very similar to office (word/powerpoint/excel/database/drawpad), but it's free! And it's completely compatible with all of offices files. If you have the silly trial versions, or are still using Office 2003, look into this, it downloads fast, installs fast (no restarting), and is easy to get accustomed to.
I don't feel like paying 300 dollars for microsoft's bullshit.
