Thing 20

ThinkFree Office looks really great compared to Google docs, a lot more sophisticated, and better still, appears to operate as a pdf writer. It's an excellent choice for basic home use. It uploads documents easily, and while it won't edit pdf documents, it will allow you to select text, copy and paste. It is a little slow to set up, but I think it's a better option than cheap desktop software (MS Works for example) for those without MS Office, which is extremely expensive.

Thing 19

I used Google docs to make an Easter card for Penny containing pictures of 23 eggs. I shared it with her, but oddly she could see the words but not the images. We couldn't work out why. The web link works fine though.
