Who really uses Office software on their phone?

So there is Open office (Which Google bought??) - And also a few other Office Productivity software suites available on Android. This is genius for tablets, but I just don't see me creating a whole spread sheet presentation on my smartphone, or doing an expense report, or budget spread sheet in excel.

I can however see editing a few things.

Then I saw this anyone excited? Will this be the touch friendly answer I have been looking for to make my GS3 a business power house. The only business I get done with it would be the Amazing Gmail experience provided by Google. That and of course there is the GOOD app. Other than that???
