I didn't want to explore Open Office because I don't like to download stuff that I have no intention of using. (Sorry!) However, in looking at Google docs, I think that it is very comparable to Microsoft Office and the suite that I use on my Mac. Basically, if you can function with one type, you can function with any of the suites. A definite advantage to using an online productivity tool like Google docs, is being able to collaborate much more easily than through email.
