I downloaded the CloudOn app on my iPad. I used it to edit some of the documents I have saved in my Google Drive. It's pretty cool in that it does exactly resemble Microsoft Office products. However, here's the thing, I despise typing anything on my iPad. If it's going to be longer than a sentence, I want a real QWERTY keyboard. I don't care for typing long things on my smartphone either, but at least it's a little bit better thanks to the Swype function.
The SignNow app seems pretty cool and a lot more functional as we move more and more into a paperless world. Perhaps someday I'll have my summer reading program performers sign their contracts via SignNow instead of an actual paper copy... you never know!
