I agree. Google Docs is mediocre at WYSIWYG and interoperability, but boy does it solve long term storage. I don't have to worry about paying for Dropbox or having local files that I can't search quickly unless I am on a Mac with Spotlight or have full indexing on Windows or the Linux equivalent. I don't have to worry about the folder structure and the files can't vanish with an SSD failure.
And, unlike text files, it's easy to insert images and tables in a Doc file.
