My brother was able to get me iWork '08 discounted from his college, and I was able to upgrade Office 2004 to 2008 using the SSD, so I have both installed on my computer. The two programs I use are Word/Pages and Powerpoint/Keynote. I use Word for essay writing and Pages if I'm creating some sort of handout or have a creative assignment. For presentations I have found myself using Keynote despite the fact that my school uses PCs and Office 2003. Keynote can export to a ppt file really well, keeping the nice look of the presentation. The only changes that usually occur are to the font. The one presentation I have made using Office 2004, the pictures did not carry over so I had to re-find them and insert them at school!
