The above video is the work of Stefanie Newell. It came across my desk courtesy of The Book Designer's Carnival of the Indies monthly link post, and I thought it might be useful to readers.
I use Google Docs all the time; it's not just a pretty decent Office alternative, but also a good tool for collaborating with other writers. Also, its mobile apps make it really easy to switch between reviewing a Doc on my iPad while typing in changes on my laptop. (Yes, I could review the Doc on my laptop, but I tend to lean back when reading on my iPad, and that creates a completely different mindset from when I lean forward to type on my laptop.)
I have had trouble getting some to use Google Docs, though - even on the level of reading my notes. Luckily I have found it's easy to export a Doc with the notes attached.
What do you think of Google Docs? Is is good enough to produce a manuscript?
