Been running Open Office for better than 10 years ( ported for Linux ) on all my Macs except the Quadra which still runs Semantic Greatworks.
Works 200% better than anything Microsloth has on offer.
Opens faster, reads everything I ask it to.
Has very few holes for hackers to use to get into my computers.
Writes to really a small efficient file sizes ( about 1/2 to 1/3 the size of a word file ).
Not as pretty, but pretty is bulky and slow.
Welcome to the future Ric.
You will find it is a lot better than Word as well once you get used to it.
Unless you use Word as a poor quality DTP.
