Computers are handy for writing. The only problem is a typewriter won't jam up and not be able to save your file. Then again you can't easily make backups when your only copies are on paper. I'm sure we've all lost work due to computer errors and whatnot. What's the most you've ever lost? Are we talking pages, chapters? Entire books? I save and backup so often that I can't even remember the last time I lost a good deal of writing. I don't think I've ever lost more than 5-10 pages max at once.
