As a court reporter, I deal with documents. There are some pretty good office apps out there that rival Microsoft Office that's installed on my laptop at home, so I can create documents on my iPad to be edited later on my laptop.
I'm on the go a lot, and I like the idea of working on a project when I'm not able to be near my computer.
Saving that work to be opened later on my laptop was a pain. In order to move my iPad document to my laptop, I typically emailed it to myself. It's an extra step and it worked pretty good most of the time. That is, until it was too large of a document to email.
Ugh, Houston, we have a problem.
