I am gettting a new macbook pro, and apple is giving a $30 off on iWork '09. I am just considering iWork '09 just because of this one-time discounted price I will get. I am not sure if I will miss this in future if i don't buy it. Anyways, I plan to install ms-office and openoffice. Currently, in my PC, I use mostly excel and rarely word and ppt. Do you folks have any feedback of having ms-office, openoffice and iwork '09 installed? and which one do you use alot if you have all three installed? Thanks a ton in advance.
