I only learned to touch-type in my late twenties. It took my about two weeks of practising with gtypist for 20-30 minutes a day. I only type about 50-60wpm when I push myself (usually quite less), but even if you can only type 30wpm it's still an enormous improvement over hunt-and-pecking. It makes me cringe to think they're "teaching" MSOffice to school kids but can't be bothered to teach them basic typing skills.
