I think the beauty of typing is that backspace and correct is so much easier than erasing and fitting a correction in the erased spot. So when you check over your work and want to fix a mistake it is so easy when word processing and more difficult when writing so might not be worth the effort when writing...thinking of a mistake where you want to change one word to a longer phrase or a longer phrase to one word or just inserting a missed word. And I think it is easier to actually see mistakes in the typed paragraph than in a hand written one.
