A recent profile in the Sunday Times of Don DeLillo revealed one his writing quirks is to write only one paragraph per page on his typewriter (yes, that's another quirk--he still uses a typewriter). He says that this allows him to see the words almost as art: "The shapes of letters began to attract me," he said. "I began to notice the shapes and sounds of letters within words--not only the sound and the meaning it created, but the look of a particular set of words."
As an example he gives the phrase, "the raw sprawl of the city." He says, "I see the word 'raw' inside the world 'sprawl' and I like this, it seems right."
The one paragraph per page approach might be useful if you want to see your work anew, maybe after you've done the first draft and are hoping to craft it more carefully...I'd be up for trying that, but I don't think I could ever go back to a typewriter.
