I don't have OO available except at my desk, so it is better when I'm going to be away

The other thing that "catches" me surprisingly often is the bundle format of OO file. Well, I think its called a bundle. From the command line, the OO file is actually a folder. So for emailing, copying to USB, etc, I frequently forget to archive the folder and instead end up with an unusable alias. Plus, it's a bother to have the archived version that is distinct from my actual working doc. This isn't a problem with a text file.
