i'm using Cloudon and so far it's the closest to having MS Office loaded that's available. I use Excel quite a bit for home and work and Word and Powerpoint for school. Word does not double space per most professor's requirements.
BEWARE! Although the developer boasts autosave, it does not. You must manually use what they call the Autosave
bars in the top left corner of the app and do it often. Otherwise you can receive the dreaded "there seems to have
been a connection glitch" message and all that is saved of your doc is the title. I'm sure they will fix these things
