Now imagine a machine is malfunctioning and you need to look up the last known "good" settings to see if anything changed. First open a browser, then go to the office site, then fish out your cell phone because you're going to need the authentication code to log in, then dance around for a bit because you're in a warehouse and the reception is terrible, then open the Word app, then wait ages for it to "work on it".
All I'm trying to do is quickly read some text. I don't see how this is better than clicking a text file icon on the desktop.
