Not everyone has a brand-new computer; The manuscript of the book I'm about to publish is in Open Office Word, about 400 pages and full of large images, and autosave is a real pain because it takes minutes to save the file.
Like another commenter said, I wouldn't make it the most important thing, overall efficiency is. But software speed is important to anyone with an older computer, especially a Windows computer, because the computer slows as the registry grows, and the registry never gets smaller, only bigger.
