I found one of them useful. It basically does something that I've set Ubuntu up to do: press some keys, select a portion of the screen, take a screenshot, put it on the web, copy the URL to your clipboard. It's (obviously) very useful, but it's slightly amusing to me that the software costs money. With Ubuntu, I had it setup with Compiz, a perl script, and Dropbox.
Shovebox looks sort of interesting, and I might try it out, but the rest of it doesn't interest me. The word processor might, but I think that it's not a good idea to be unequipped with something compatible with office these days.
