Do We Need New Formatting Guidelines?

I'm sure you've seen them, on our website and other websites and in many publishing how-to books: formatting guidelines. Margins of 1 inch all around. Courier typeface, 12-point. Etc., etc.

But in the age when most editors and agents may be reading your manuscript on a Sony Reader or other electronic device, do we need new formatting guidelines?

In our office, I have a Sony Reader, which does a great job with Word documents. It reads them fine and resizes on the fly. But my intern's Kindle only reads PDF files and the type is tiny unless we reformat them carefully to be read in the Kindle. Obviously the best solution would be for Amazon to enable Word document reading on the Kindle, but I suspect they won't be doing that for a while.

So, should we start requesting that manuscripts be formatted differently so that we can more easily read them on the eBook readers? Or is it the job of the agent or editor to reformat and convert so that we can read them?
