Our choice is...
1) Google Docs
2) Libra Office
Depending where we are and what O/S we are using.....
Google Docs if we are accessing from a windows 7 machine
Libra Office if we are accessing from a Linix machine (we use ZORIN 6 Ult)

Company users were asked if they want WIN8 and Office 2013 ( we trailed for one month) ANSWER NO No no.......

So Microsoft you have your answer sorry we will NOT be using WIN8 and/or Office 2013.
