Foothead:
i disagree about it being terrible at viewing office files. to me it shows it just fine. if you want to edit it, you will have to convert it to a google docs format, which is does automatically if you choose to open it in Google docs instead of just the inbuild word viewer like application.
Hardhead:
if the only thing you want to do is to open the file, then word viewer is properly the best option.
it was just if you wanted an alternative to MS bullshit office, then you should use check out Google drive.
Libre office is also good. no doubt about it. i just favor GDrive
