Cell phone novels?

Since I'm one to hate texting--not because I'm a luddite in any sense...I just suck at it--I'm pretty sure I won't be catching on to this new fad. 

Cell phone novels

Use your phone to write a novel or short story, then upload it and sell. Perhaps get it converted to paperback and into stores. While this seems to be a Japanese phenomenon at the moment, no doubt there are people doing it here in the U.S. as I type. 

And, of course, you have the dissenters:

Some literary purist don't think the cell phone novels constitute real literature, but their popularity is undeniable.

Question is, does it really matter how a story is typed/written to define it as literature or not? I understand some people's qualms about stories written entirely in chat lingo (btw, omg, roftl), but if someone composes a good story with their Blackberry instead of a typewriter, isn't it still a story? And would you put in the effort to write a manuscript entirely with your thumbs?

I see that smile.
