I'm trying to think of why it would be a good idea.
The Washington Post's (or was it the Associated Press?) app for the Watch used to display entire articles. Laid out on the floor, they probably would have scrolled for ten feet. It was a pain -- it hurt -- to try to read through them, even when I was sitting on the toilet first thing in the morning. I gave up and removed the app after just a couple uses.
Why would you need to see a .doc file on a tiny screen like this? What do you expect to gain? Why isn't the phone good enough?
